[PATCH 03/20] [main] fix bug with multiple deactivate commands

[Scott James Remnant]

If plymouth deactivate is called when we're waiting for the boot
splash to become idle, we end up asserting that there's not
already an idle trigger.

Fix it by checking for an existing deactive trigger, and if there
is, ignoring the new deactivate command (except for pulling its
trigger so it doesn't block).
