URI validation errors wipe out fileset uploads when creating a work

[eporter23]

Describe the bug
A clear and concise description of what the bug is.

Our form validation for URI entries seems to wipe out fileset uploads during an editing or creating session in which new filesets have been added. These seems to occur in all environments, and may be a longstanding bug that is unlikely to occur often.

To Reproduce
Steps to reproduce the behavior:

1. Create a new work
2. Fill out required metadata in the Descriptions tab
3. Enter an incomplete URL in a url-validated field (e.g. rights documentation)
4. Click over to the Files tab and upload a file
5. Click on the deposit agreement checkbox
6. Click save
7. See the invalid URL alert message
8. View the Files tab and note that the file upload has disappeared

Expected behavior
A clear and concise description of what you expected to happen.

The URL validation error message should appear when a form field entry does not validate, but should not remove uploaded Filesets.
