Fix stuck HDMI-CEC actions after boot

Ensures that all queued actions on local devices are started after
boot. Previously, an unstarted SendKeyAction could stick around after
boot, blocking any future SendKeyAction from being created.

Bug: 193188675
Test: atest HdmiControlServiceTest#normalBoot_queuedActionsStartedAfterBoot

      manual test: spam volume up on boot with IR volume control enabled
