for-each-ref: fix segfault in copy_email
You can trigger a segfault in git.git by doing:
git for-each-ref --format='%(taggeremail)' refs/tags/v0.99
The v0.99 tag is special in that it contains no "tagger"
header.
The bug is obvious in copy_email, which carefully checks to
make sure the result of a strchr is non-NULL, but only after
already having used it to perform other work. The fix is to
move the check up.
