luci-mod-admin-full: fix initializing realtime graphs

Commit 69782ccbc ("luci-base: xhr.js: defer starting poll queue") changed
the way XHR poll queues are started which broke the timing on the realtime
graph pages.

Fix the problem by manually starting the poller after registering the request
handlers.
