Don't need to init testr explicitly

[Kui Shi]

In run_tests.sh, function init_testr will initialize testr if the
directory .testrepository is not existed. Actually, testr will do
the check before run the test:

In Python package testrepository, setuptools_command.py:Testr.run

68 def run(self):
69 """Set up testr repo, then run testr"""
70 if not os.path.isdir(".testrepository"):
71 self._run_testr("init")

So, init_testr can be removed safely.
