Subject: [PATCH] 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 05f1eff1c9c3f82797f1a0f92ff7665b9f463488)
(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:e0b5a793a19198370d479401101cea97c2f1d835)
