Fix hidden live location timeline tiles after text messages

This prevents `MXEventTypeBeaconInfo` events from being added into other
bubble cell data objects.

Previously, when starting a live location share right after
sending a text message, the beacon info event would get appended into the text
message's bubble cell data which prevented it from rendering.

Similarly, when restarting the app in such a situation the events would be getting
reprocessed _in backwards order_ which meant the final beacon info landed in
its own bubble cell data (causing it to render) but a beacon info right before the
text message would now get combined with the text message causing it to go hidden.
