AcquireNotify and StartNotify starts notifications and/or indications
by whether the characteristic supports them. Before this patch, if both
were supported, Bluez would try to start both simultaneously. This
patch changes this behavior so if both are supported, only
notifications are started. Test cases have also be updated accordingly.
