In the ModulesController and MenusController, there are some variables initialized/defined but not being used at all (It can be seen easily from smart IDE like phpstorm). This PR simply remove it.
Testing instructions
I think this PR just need a quick review from PLT and then it can be merged. However, if you want to test, just apply this PR, login to backend of your site, access to Menus -> Menu Manager, Extensions -> Module Manager, make sure these two pages still being displayed property and test is success.
Works as described
