v0.42.1

Notable changes:

Application loading screen
  - We now properly process read receipts, delivery receipts and other
    types of sync messages before dismissing the screen.

Fix: Properly report decryption errors when they happen

Fix: Slow down expiring message processing, especially on startup (may
  result in lower CPU/memory usage)
