Warnings when pushing to testsuite

[Jan Stolarek]

When I'm pushing to testsuite repo I get lots of warnings:

Notice that warnings refer to github:

remote: To git at github.com:ghc/testsuite.git
remote:    ccc29fb..67d6a19  master -> master

Any idea why this happens? I don't get warnings when pushing to main GHC repo.
