Canceling 'from insert URL' is causing a bug

[olegfedak]

Describe the bug I have been experiencing an issue with an existing image in the field widget. When I'm opening it to insert an image URL but then clicking cancel, the image gets lost.

To Reproduce Assuming, there is image added through image widget before.

1. Go to 'field widget image'
2. Click on 'Insert from URL'
3. See modal window
4. Click on 'Cancel'
5. The image is lost

Expected behavior 'Cancel' just closes modal window.
