Update JGit to 0.7.1.34-gf36df5d to fix empty tree bug
Update JGit to 0.7.1.34-gf36df5d to fix empty tree bug

Older versions of JGit, including the one we used within Gerrit,
failed to pack trees or blobs which appeared after an empty tree was
referenced in another tree.  Normally there should never be an empty
tree in a Git repository, but buggy versions of EGit have been known
to produce these (likely due to a different problem within JGit).

Newer versions post 0.7.0 have this fixed.
