Fixes a performance bottleneck in `ConversationFragment` caused by expensive calculations in `ConversationItemDecorations.hasHeader()`. This method is invoked in `RecyclerView.ItemDecoration.getItemOffsets()`, which runs on every layout pass and happens frequently during scrolling.
The most expensive calculation in `hasHeader()` is `toEpochDay()`. That method calls `Long.toLocalDate()`, which clones a `TimeZone` object on each call. Upon opening one conversation (without scrolling), I observed that `toEpochDay()` was called over 1000 times in less than a second, rapidly allocating memory and causing garbage collection pressure that potentially leads to ANRs.
We only need to calculate `hasHeader()` once for each conversation element, so caching the result of that method will eliminate the unnecessary calculations and improve the memory usage of `ConversationFragment`.
It is expected that when a user search for a message, that all the
matches within the same messages are highlighted (if there are more than
one match) not just the first match. This is also consistent with how
the search in the desktop app is implemented.
Resolves#13960
This fixes an edge case seen on ConversationFragment, where if the
device time format is switched between 12/24 hour format while the app
is running, the old time format will still be displayed when the app
is resumed.
This is due to a design flaw in `DateTimeFormatter.ofLocalizedTime`,
where the time format is statically cached and not updated upon
configuration change. The `LocalTime.formatHours()` extension method
was updated to no longer rely on the misbehaving `ofLocalTime` method.
In addition, `ConversationMessaageComputeWorkers.recomputeFormattedDate`
was designed to skip recomputing non-relative timestamps. This works
in most cases but not this specific edge case. A `force: Boolean` flag
was added to force all items to be updated. And the `force = true` flag
was passed upon `onResume` of the fragment.
