To reproduce:
1. Create 2 sessions.
2. From either session, run a random `RUN_COMMAND` intent command with `am` command and shift to the other session.
Termux app would crash and throw the `The content of the adapter has changed but ListView did not receive a notification.` exception. TermuxService was previously not notifying the ListView of the sessions list that a new session has been added, if the activity was in foreground.
