name_to_object in fun.py does not handle packed-refs

[Gustra]

Sometimes references are stored in the file .git/packed-refs. The code in fun.name_do_object() does not handle that case, causing BadName exception.

Thanks a lot for reporting.

Would you have a few lines of code that trigger said BadName exception? That would also allow to post a workaround right here until there is a fix.
