git-gui: prevent double UTF-8 conversion

Browse source 
Convert author's name and e-mail address from the UTF-8 (or any other)
encoding in load_last_commit function the same way commit message is
converted.

Amending commits in git-gui without such conversion breaks UTF-8
strings. For example, "\305\201ukasz" (as written by git cat-file) becomes
"\303\205\302\201ukasz" in an amended commit.
