Collaborator cannot revert to previous version

[Description]:

When a Collaborator tries to revert a file created by a different user to a previous version for the second time, there is an error displayed (see pic attached). The customer is expecting to be able to revert the file.

[Steps to reproduce]:

Use a PNG or DOCX file

1. create a default test site
2. create 2 users and add them to the site as collaborators
3. User A (Collaborator) uploads a document doc1 (version 1.0)
4. User A uploads a new version for doc1 (version (1.1)
5. User B (Collaborator) reverts doc1 to version 1.0 (version 1.2 gets created)
6. User B tries to revert to version 1.1. Gets an error message that version could not be reverted.
