Fixed save/cancel buttons when edititng VM thru relationships.

- Fixed save/cancel button on Edit VM screen that broke when button_tag was added to the form, had to remove form_tag tag to fix the issue.
- Removed image_submit_tag tags inside the if block to move fields left/right that were no longer needed, link_to tags to move fields left/right work for both explorer and non-explorer screens.
