RESTRICT AUTOMERGE: Catch exceptions from setLockCredential()

When LockPatternUtils#setLockCredential() fails, it can either return
false or throw an exception.  Catch the exception and treat it the same
way as a false return value, to prevent crashing com.android.settings.

Bug: 253043065
Test: Tried setting lockscreen credential while in secure FRP mode using
      smartlock setup activity launched by intent via adb.  Verified
      that com.android.settings no longer crashes due to the exception
      from LockPatternUtils#setLockCredential().
(cherry picked from commit 05f1eff)
(moved change into ChooseLockPassword.java and ChooseLockPattern.java,
 which are merged into SaveAndFinishWorker.java on udc-qpr-dev and main)
(cherry picked from https://googleplex-android-review.googlesource.com/q/commit:5f07aba15008e2681d5a10435dc5e1485863f21f)
