Invoke strong auth callback and default strong auth expired to true

Split off from I0af11da1b7cd7c8d837bc5ba3a62ef2ffca74b1b.

The initial value did not matter previously because
a SystemUI crash triggered the boot logic and forced
a manual entry before fingerprint works.

Long term the timeout logic should be moved to StrongAuthTracker
so it can be shared with the trust agent implementation (currently
implemented by the trust agents themeselfes)
