From: Lars Schneider <lars.schneider@xxxxxxxxxxxx>
If git-p4 tried to store an empty file in GitLFS then it crashed while
parsing the pointer file:
oid = re.search(r'^oid \w+:(\w+)', pointerFile, re.MULTILINE).group(1)
AttributeError: 'NoneType' object has no attribute 'group'
This happens because GitLFS does not create a pointer file for an empty
file. Teach git-p4 this behavior to fix the problem and add a test case.
