hitting enter in a metadata field removes files

[rjkati]

Descriptive summary

When I create a new work and add files, hitting enter in a metadata field will remove the files.

Expected behavior

Hitting enter in a metadata field causes files to be removed

Actual behavior

Hitting enter in a metadata field should preserve all files

Steps to reproduce the behavior

1. Go to Dashboard -> Add New Work
2. Go to the Files tab and add one or more files
3. Go to the Descriptions tab and type a value in the title field
4. Hit Enter while your cursor is still in the title field
5. Navigate back to the Files tab and observe that your file is no longer listed.

This behavior occurs for both required and optional metadata fields. I was able to duplicate this behavior on dev.nurax (4.0.0.rc3) and stable.nurax (3.5.0)
