- If SysUI is restarted (ie. during dev or a crash), the components
registering the shell listeners may not be aware of this, and
listener callbacks will not be re-registered. Currently all the
listeners are managed correctly (bound & later unbound) so we can
just keep the active listener references to re-register if this
happens.
Bug: 207142749
Test: Kill SysUI, start some apps and ensure Launcher still shows them
in recents
