Let unlocked profile verifyCredential under unified lock

Let unlocked profile verifyCredential under unified lock

When unified work challenge is enabled and the primary user is unlocked,
LockSettingsService should unlock the managed profile subsequently by
calling verifyCredential() in most cases.  Previously,
verifyCredential() is not called on managed profiles when any one of the
two conditions are met:
  1. when the profile is not yet running
  2. when the profile is already unlocked
These were introduced to make sure the managed profile stays locked when
it is in QUIET_MODE (i.e. work mode off).

However, condition 2 is problematic. Specifically, it also prevents auth
tokens, etc., from being refreshed (side effects of verifyCredential()),
even when the profile is not in QUIET_MODE.

We remove condition 2 in this change to make sure verifyCredential() is
still called on the managed profile when it is RUNNING_UNLOCKED.
Condition 1 alone should be able to handle the QUIET_MODE case.  Unit
test is also updated in case regression occurs.
