Checking whether required metadata is filled in not working properly.

[ddey2]

1. Make sure there is a metadata definition for file with required field, and not required field
2. Try to upload a file
3. Just enter the optional field => It enables the Next button (Indeally it shouldn't)
4. Restart and try to fill in required field. => It enables the Next button (Indeally it should, so it works in that case)
5. Remove the required metadata => The next button remains enabled
6. Try to click on Next => It allows to upload file (Indeally it shouldn't unless you add the reuqired field for the metadata)

Something odd.

When I created a metadata definition that was not required for files, I would see 'update' and if I did not fill in the required field (just the optional one) I got an error.

Looking into this, figuring out what is different for this case.
