Database is immediately changed after open

[varjolintu]

Overview

Regression from #11410. The database looks like it has been changed right after it has been opened. I'm not using Touch-ID which the PR is related to.

I don't have any Touch ID hardware connected to the computer, but if the Touch ID / Quick Unlock feature is enabled in KeePassXC settings, Database::publicUuid() triggers the change. The only unlock option I have is the default database input.

Also checked that the context.biometryType returned by canEvaluatePolicy is kLABiometryTypeTouchID which is definitely not correct.

Steps to Reproduce

1. Open a database
2. See that the database is immediately changed even if user has done nothing

Can be reproduced if a normal keyboard is connected to a Mac Mini or some other Mac that does not have integrated Touch ID.

Expected Behavior

Database should not be changed on open.

KeePassXC - Version 2.8.0-snapshot / 2.7.10-snapshot
Build Type: Snapshot
Revision: ca9b88f

Operating System: macOS
Desktop Env: -
Windowing System: -

This could be the database being assigned a public uuid

If I save the database and reopen it, the issues does not happen again.

This happens when quick unlock is enabled on macos even though it doesn't actually work (ie, when you don't have touch id or watch to initiate quick unlock)

I'm pretty sure this is some kind of macOS bug because the value of context.biometryType is LABiometryType.touchID right after the context initialization. The default value should be LABiometryType.none
