We avoid calling to the db onCreate. This change has the same UI, as setTheme was always appCompat_DayNigh_NoActionBar called after the check for instant login
We alread have Transport.shouldBeUsedInstantly to define a transport allowed to be instant. And, only screen lock may be allowed ATM
Screen lock was effectively force as instant as soon as a key with the rpId was registered with screen lock. As so, even if the allowList is empty (this isn't an authentication for a given account, and the user may want to login with a hardware key) or if the allowList contains a key that isn't for a screen-lock (e.g. USB)!

This part was doing work on the UI thread, including DB requests, and redundant: setTheme is called right after the condition to set AppCompat_DayNight_NoAction_Bar, the statusBarColor seems to not have any effect, and setting the background color can be done in the suspended handleRequest

INSTANT_SUPPORTED_TRANSPORTS was redundant: this is already what shouldBeUsedInstantly does. (And only one transport never return false: the screen lock, but that isn't relevant)

And here the 2nd part "If there is any key for that website in localSavedUserKey, go to signInSelection" => we can't use a USB or NFC key, even if it is the only allowed key

This is the part where we want to be able to choose which account to use during sign-in, but we don't want that view during registration
The previous selection of user account was with the other bug, where it was "there is any key for a website => we go to the account selection for screen lock login".
The current behavior is now:
- "we have an allowCredential => use it"
- "we don't have an allowCredential, go to transport selection, select screen_lock, select user account"
- "we don't have an allowCredential, go to the last transport for this account login or go back to transport selection, select screen_lock, select user account"

I had 2 problems with the current implementation:
This is because of
localSavedUserKeythat makes the authentication use instantly the screen lock if we have a key saved for the domain.This PR fixes these 2 issues. And does a little cleanup, and a few comments to help understand what does what
MEMO: I use fido-core as a library.
