silently ignore feed issue on ajax request

[techtimo]

currently:
{"error":true,"title":"tt not found in DB","message":"Change the 'devices' attribute of your Shortcode"}

instead:
silently ignore (maybe print a console log)

also capitalization should not matter during ajax calls
If the feed is called Martin but martin is stored, we should get martin points and martin should be displayed in the frontend
