Registers noscript to check for updates on first run

We refactored our code to make sure we register all addons for checking for updates AFTER we are bootstrapped, but the order of execution for the code, that is triggered before we install noscript from the shipped file on the first run, so noscript is no scheduled for an update check on first run.

we should re add the manual queing of noscript in our TorBrowserFeatures so that even on first run the system will check for an update for it after bootstrap
