    Allow to specify multiple tests in run_tests.sh

    Disable checking for unbound variables, as there is possibility that no
    tests were specified. Example invocation:

    run_tests.sh -n -t fuelclient/tests/test_client.py:TestAuthentication.test_wrong_credentials \
    -t fuelclient/tests/test_client.py:TestDownloadUploadNodeAttributes

    Additionally align shifts in getopt loop and remove
    dead return from tox invocation.
