Tor in-process restart fails to write auth cookie

I integrated latest Tor master on 2018-03-15 into Tor.framework resp. OnionBrowser 2. Shutdown with the improved SIGNAL SHUTDOWN seems to work just fine.

When restarting Tor, however, it turns out, that the auth cookie is not written to the file system on the second time. First time works, file obviously gets deleted on SHUTDOWN but is not recreated on second start.

There is an according log entry the first time:

[info] init_cookie_authentication: Generated auth cookie file in '"/var/mobile/Containers/Data/Application/0653FD89-2D17-477A-B541-FC53F1A29EBD/Library/Caches/tor/control_auth_cookie"'.

This is not appearing on restart.
