From: M Hickford <mirth.hickford@xxxxxxxxx>
Previously, credential-cache populated authtype regardless whether
"get" request had authtype capability. As documented in
git-credential.txt, authtype "should not be sent unless the appropriate
capability ... is provided".
Add test. Without this change, the test failed because "credential fill"
printed an incomplete credential with only protocol and host attributes
(the unexpected authtype attribute was discarded by credential.c).
