Test for leading space in citekeys

This test is expected to fail. Nose does not handle that yet (treats it as false).
As such, changes have been made to make tests discoverable by unittest.
You may want to uninstall nose and do something like:
alias nosetests="python -m unittest discover"
in your bashrc
