Add null check for voiceInteractorComponentName.

Browse Source 
Voice Assistant can be disabled on a user-level. Adding this null check
prevents crash for when Assistant is enabled for the system in general but
disabled for a specific user.

Bug: 149112015
Test: Manual -- Change config_disableLockscreenByDefault to true to
emulate the environment in which Volvo observed the bug. Verify that
switching to user0 through adb shell switch-user 0 causes the same crash.
Verify that the crash does not happen with the new null check.
