[PATCH 1/2] test: mailmap can change author name without changing email

[Jonathan Nieder <jrnieder@gmail.com>]

From: Felipe Contreras <felipe.contreras@gmail.com>

A mailmap entry of the format 'A U Thor <email@example.com>' has two
effects: (1) 'A U Thor' becomes the canonical author name for commits
with author address 'email@example.com', and (2) 'email@example.com'
becomes the canonical author email for commits with author name 'A U
Thor'.

We already have tests for the effect (1) in the committer name, but
not in the author name, so the tests do not cover the shortlog and
blame codepaths as they should.  Fix that.

[jn: simplified by reusing Committer mailmap entry, clarified
 description]
