Git Linked Repository Authentication Type "None" Ignored

When using a linked repository with repository host Git, selecting the "None" type is ignored if there is information in the Username field. To reproduce:

1. Set up a linked repository with Repository Host Git
2. Select Authentication Type "Username/password" and enter information into fields
3. Select Authentication Type "None"

Results: Repository tries to use entered Username/password to connect to Git repository
Expected: Repository is accessed anonymously as specified in documentation for "None" Authentication Type

Work Around: Select Authentication Type "Username/password" and manually clear out username and password fields. Select Authentication Type "None" again.
