Fixed drag-n-drop reorder of gallery images not responding to drops

Browse source 
no issue
- https://github.com/TryGhost/Ghost-Admin/pull/1081 introduced a bug where the `insertIndex` was being cleared every time we showed the drop position indicator because we hide the indicator as a reset every time we show the indicator. This meant every drop was missing the required insertIndex.
- added a flag to the `_hideDropIndicator` function so that a reset when showing the indicator doesn't clear the required information
