Show thread on latest message

Use the new thread functionality in libQuotient to show the thread on the latest message rather than the root.

Note: to test you need to bump your libquotient minor version to 10 or higher.

Also Note: this reveals some other bugs in how new threads are shown or refreshed when new messages are added, this will be fixed in a later patch as some re-architecting is required
