No nedd to init testr explicitly

[Kui Shi]

    Don't need to init testr in run_tests.sh

    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.
