[MOS-593] Fix backup issues with DB

Backup had some issues when filesystem was not clearly closed.
After that, sqlite was not commiting the transaction while
doing VACUUM INTO query, which caused fail on the next
query. Fixed by commiting the transaction when there's
any ongoing one during backup.

[MOS-210] Avoid blocking of key handling, artificially generate Release

In rare cases when corresponding Press and Release key events were not
generated the logic prevented other keys from being handled. Handling of
other keys is no longer blocked.

In addition to the above Release event is artificially generated. This
ensures that key presses are not ignored if there were no real Release
event. Typically this may occur when keys are pressed fast one after
another. A side effect is that when a key was pressed while other one
was already pressed then both of them are handled by the UI which
prevents e.g. letters from being ignored while writing.
