image formatters not showing external images

an update to the patch for if there is no url set yet

I think the problem is the 'itok' query at the end because I'm seeing this problem surface on a site here as well, so will dig in a but further to see what happens.

I recently ran into an error with the image formatter being hijacked where there is no image style... this occurs when the content display for the image field is set to show "original" so no image style is there to be applied.
