Fix ChooserActivity stuck disabled

If a device upgrades straight from TM QPR3 to UDC it would get stuck
with ChooserActivity disabled. This change returns ChooserActivity to
its default enabled/disabled state on boot. This class can be safely
removed once there are no longer devices upgrading from TM QPR3.

Test: Flash device to TM QPR3 with wipe
Test: Fully boot the device
Test: Flash device to UDC (including this change) without wipe
Test: Fully boot the device
Test: $ adb shell pm resolve-activity -a android.intent.action.CHOOSER
Test: Observe that the intent resolves to
com.android.intentresolver.ChooserActivity
BUG: 283722356
FIX: 283722356
