This replaces multiple stubs with a single stub on the lower level
API client method to return the desired set of templates. You can
see this most clearly in the diff for the "_sms_sender_" test:
- Add a stub for "get_service_templates"
- Remove stubs for "all_templates" and "get_templates"
In order to make the change, I had to separate the reply-to set of
tests from the "_things_right" tests because "count_of_templates"
was actually in conflict with "count_of_email_templates". To make
the new test I copied the original and removed unnecessary stubs
from both of them depending on what's being tested.
I'm not sure what the "_things_right" test name means; the name of
the new test is at least consistent with others in the file.
Note: I also removed the "assert mock_templates.called is True"
lines as they wasn't adding any value that I can see.
