[PATCH 1/2] Add test for ls-tree with broken symlink under refs/heads

[Petr Stodulka <pstodulk@redhat.com>]

git ls-tree goes into an infinite loop while serving pretty vanilla requests,
if the refs/heads/ directory contains a symlink that's broken. Added test
which check if git ends with expected exit code or timeout expires.
