Remove unneeded first time redirect

Using the out-of-the-box first time redirect plugin causes the
healthcheck plugin to respond with a 302 Redirect, when deploying a new
gerrit instance.

This, in turn, might cause the gerrit instance to be considered
unhealthy since typically 302 is not considered a successful code.

Remove unnecessary first time redirect plugin so that Gerrit stops
responding 302 to the first healthcheck attempts.
