Fix tag reference name in testrepo.git

The git test repository was holding a wrongly named tag reference ("very-simple") pointing at a tag named "e90810b".
This mistake (mine :-/ ) originates back to https://github.com/libgit2/libgit2/commit/9282e92

Whole credit goes to @tclem for having spotted this.
