Fix crashing on starting and quitting
QCollator (especially with Qt 5.14 and ICU 65.1) is very unhappy with threads. To avoid having to lock and unlock the mutex everywhere (and ensure it is unlocked before calling other things that might lock it, etc.), we do it as locally as possible. Even if for some reason Qt and ICU make QCollator threadsafe in the future locking here should have minimal impact. BUG: 419585 Differential Revision: https://phabricator.kde.org/D28659
