There is no change in functionality in this commit.
Apart from clarifying what the timestamp means (it's the timestamp of the
*sender*), this intentionally breaks all the call sites, so I could have a sane
way to thoroughly audit wherever we're passing in timestamps, to see where
we're depending on them to affect sort order.
For the sake of a cleaner diff of meaningful changes, instead of "fixing"
everything in this commit, I've just added comments and renamed signatures.

There are multiple places in the codebase we present a conversation.
We used to have some very conservative machinery around how this was done, for
fear of failing to present the call view controller, which would have left a
hidden call in the background. We've since addressed that concern more
thoroughly via the separate calling UIWindow.
As such, the remaining presentation machinery is overly complex and inflexible
for what we need.
Sometimes we want to animate-push the conversation. (tap on home, tap on "send message" in contact card/group members)
Sometimes we want to dismiss a modal, to reveal the conversation behind it (contact picker, group creation)
Sometimes we want to present the conversation with no animation (becoming active from a notification)
We also want to ensure that we're never pushing more than one conversation view
controller, which was previously a problem since we were "pushing" a newly
constructed VC in response to these myriad actions. It turned out there were
certain code paths that caused multiple actions to be fired in rapid succession
which pushed multiple ConversationVC's.
The built-in method: `setViewControllers:animated` easily ensures we only have
one ConversationVC on the stack, while being composable enough to faciliate the
various more efficient animations we desire.
The only thing lost with the complex methods is that the naive
`presentViewController:` can fail, e.g. if another view is already presented.
E.g. if an alert appears *just* before the user taps compose, the contact
picker will fail to present.
Since we no longer depend on this for presenting the CallViewController, this
isn't catostrophic, and in fact, arguable preferable, since we want the user to
read and dismiss any alert explicitly.
// FREEBIE
Attachment downloads can fail on slow networks or if the app crashes.
It's unlikely that the users response to this would be to delete the
attachment pointer, so it doesn't make sense to surface that as a
primary action.
If a user does want to delete the attachment, as always they can
long-press to delete.
// FREEBIE
- Prefer checking `.isEmpty` rather than `.count == 0` for Swift collections (can be more optimal)
- Avoid comparing `BOOL` explicitly to `NO` (considered bad practice since `BOOL` is a `signed char`)
- Specify unused `SGX_FLAGS` as `__unused` to silence warnings
