Fix H202 assertRaises Exception

Align the hacking version between test-requirement and global requirement.

The change of H202 detection from 0.6 to 0.7 in hacking is:

-    if logical_line.startswith("self.assertRaises(Exception)"):
+    if logical_line.startswith("self.assertRaises(Exception,"):

then more cases are detected by this change. Fix the exposed H202 error.

There is a special test case:
tests/v3/test_endpoints.py:test_update_invalid_interface

ref = self.new_ref(interface=uuid.uuid4().hex)

this line can not generate proper parameter for self.manager.update,
add a parameter "endpoint" for it, according to the
definition in keystoneclient/v3/endpoints.py:EndpointManager.update.

Otherwise, there will be following error after changing the Exception
to exceptions.ValidationError:
TypeError: update() takes at least 2 arguments (6 given)

Fixes Bug #1220008
