MinimizeAfterUnlock also when unlocking through browser

The MinimizeAfterUnlock setting added in #3439 closes the main window
after unlock. However, when the unlock is triggered through
KeePassXC-Browser, a password dialog is shown on top of the main window
and the main window remains open after the unlock. This is fixed
in this commit.
