Replace window.location with the full URL to prevent passing query parameters

* Example before:
location + '/mark_as_solved'
/request_for_comments/30885?locale=de/mark_as_solved

Now: //localhost:3333/request_for_comments/30885/mark_as_solved

Note: https or http will be added automatically by browsers

app/views/request_for_comments/show.html.slim
