Properly handle Windows Hello errors

Browse source 
The KeyCredentialManager::RequestCreateAsync call can fail because we can end up in a situation where Windows Hello is initially available but then becomes unavailable, such as during a remote desktop session. This commit prevents a crash by moving the call into the try-catch.

Fixes #7890

Also resets quick unlock if there is an unrecoverable error. This will not occur if the user merely canceled the Windows Hello dialog.
