Avoid loading plugin bundles when running locally

Browse Source 
When using run-server.sh (server.go) and you provide a plugins command
line parameter, then the plugin bundle should not be loaded from the
server. So when rewriting the host page let's remove URLs pointing to
polygerrit_assets on the CDN host. Thus loading the bundle will fail
with 404 and normal plugin loading and rewriting kicks in.
