Fixed the bug where users were able to search for concerts on pages
where no concerts existed. By continuing a search to a page with no concerts
would return an error.

Issued fixed by finding the concerts returned from setlist.fm in the
searches_controller.rb file and then passing in the max_pages allowed to the
search page.

The arrows to continue searching are hidden if the current page <
max_pages.
removed excess comments
