ActiveSync: fixed testImport test

The testImport test must write all existing items into a file for
comparison. Normally this is done with the backup backend operation,
which does not exist with the ActiveSync backend.

This commit adds a version specifically for that backend. DumpItems()
assumes that item meta data was updated correctly and then reads their
data via ActiveSync[Calendar]Source::readItem() = eas_sync_handler_fetch_item().

Note that this is unnecessarily complex for ActiveSyncCalendarSource:
it reads single VEVENTs, parsed by ActiveSyncCalendarSource, instead
of writing the VCALENDAR produced by activesyncd directly as for ActiveSyncSource.
Will be fixed in the next commit.
