Bug: JGit Authentication is not working

[dlh3]

VCCloneTask fails when trying to clone a repository that requires credentials. The flow attempts to:

1. connect without credentials
2. prompt to supply credentials if step 1 fails.

Strangely, it seems that the JGit CloneCommand (via TransportCommand) will create a CredentialsProvider and prompt for credentials if the endpoint requires them. This makes step 2 redundant.

In any case, providing credentials through either mechanism does not work.
