Fix synchronization issue at thread start
If a newly started thread immediately exits then m_running would immediately be set to false again and the caller would be stuck waiting for m_running to become true forever. Since a mutex for synchronizing startup already exists we can simply move the while loop into it. see also: #5134 which introduced m_start_finished_mutex
