Fix docstrings for some API unit tests.
Review Request #10367 — Created Dec. 27, 2018 and submitted
Some of the API unit tests were showing up with
<URL>in the doc
strings, due to missing
@webapi_test_templatedecorators. Others had
incorrect URL prefixes. This fixes up all these, ensuring that we always
have decorators added and that they all show URLs in a consistent way.
Unit tests pass. Checked the output for incorrect content.
