Everywhere else in Gerrit, we don't bother trying to check configs for typos, we just depend on admins to set the right value. In this case, somehow I forgot to add a new config option to the checkConfig method, despite adding a warning after I had already made that mistake twice. This check is clearly not buying us anything, so ditch it. Change-Id: I7201856b6b2651ffc71f26c5409ef7255bdda331
