Since _ls is now deprecated this is removed in favour of L1, I've also taken the oportunity to replace QStringLiteral and QLatin1String with their shortened form while we're at it.
There are also a few instances where the string literal type has been switch, the general rule being to use the one that matches the function type or value being compared to avoid conversions.
ThreadModel was not updated to use pendingEventAdded the same way MessageEventModel was so new messages in an exisiting thread were not being initialised properly. This fixes it to use the updated pendingEventAdded on new enough versions of libQuotient.
Turns out trying to manage pointers in the model is a bad idea so only save eventId in MessageContentModel, events pointers will now only be obtained temporarily then discarded to avoid both creating additional copies of the event in the model and potential sources of crashes.
This also creates a basic unit test that we can add to going forward.

Note: there is still an issue where after starting a new thread the threaded messages only appear after a restart as the root event needs re-downloading from the server to get the thread info added. My plan is to tackle this next.
- Clear out unused functions
- All functions are now static
This is because we pretty much always used it in the form:
```
EventHandler eventHandler(room, event);
eventHandler.function();
```
This simplifies it all to a single call.
So at the moment this remains behind the feature flag as this only adds a threadmodel and a basic visualisation. There is much more to come to get it ready for full release.
