Investigate unused onion service error page

Since legacy/trac#19251 (moved) and legacy/trac#30382 (moved), Tor Browser now provides user-friendly error messages for onion service connections. But it seems like Tor Browser is not showing the correct error message for recently-online-but-offline-services. Tor should return 0xF2 or 0xF3 for this situation (mostlikely 0xF3), however I'm getting the normal Firefox neterror page:

Hmm. We’re having trouble finding that site.

I haven't looked at the SOCKS connection yet, so I'm not sure what is wrong.

Summary: Investigate to Investigate unused onion service error page

I am not sure what tor you tested with, but this issue is probably caused by legacy/trac#32542 (moved). The fix was not included in Tor 0.4.3.x but should be in 0.4.4.x.
