bugfix: Add Case Insensitive URL Matching for Webpages

[MKwenhua]

Purpose:

A recent bug cropped up where the page https://hiring.careerbuilder.com/portal/ppcaliforniaState300 was not getting the tables_data from Cortex. This was because the URL was saved in cortex as https://hiring.careerbuilder.com/portal/PPCaliforniaState300

For example:
https://api.cbcortex.com/api/v1/webpages/feed?url=https://hiring.careerbuilder.com/portal/PPCaliforniaState300 is now a 404 because I changed the URL to lowercase.

but this is ok:
https://api.cbcortex.com/api/v1/webpages/feed?url=https://hiring.careerbuilder.com/portal/ppcaliforniastate300

Additional Information

need to run bundle exec rake db:migrate also this could be alternatively solved just by context.params.url.downcase which may actually be more performant by a few milliseconds(possibly) .
