test: Add known-broken test for empty author name

We test for whether a quoted empty email address

    "" <address@example.com>

will show up as the address, instead of the empty string. This is
marked as known-broken, since the current behavior is to use the empty
string.

This is a new test file, since handling of unusual email addresses
doesn't seem to fit well in any of our existing tests.
