Fix authentication for gerrit-hook on stage.t3bot.de

[sgrossberndt]

Although using the proper token requests to https://stage.t3bot.de/hooks/gerrit/?action=patchset-created fail with HTTP/1.1 401 Unauthorized (while https://www.t3bot.de/hooks/gerrit/?action=patchset-created works correctly)

This happens because stage.t3bot.de has a HTTP Authentication

Should I just remove stage.t3bot.de here?
