apps: bttester: refactor notification sending

Removes os_callout_init from tester_init_gatt and variables and funcitons
related to it. Notifications/indications were sent right after peer has
subscribed for notification (or indication). This will be now handled
by calling set_value btp command implemented in another commit.
