test: check IPR search results in HTML with whitespace ignored

[microamp]

fixes the issue raised in #7836 (comment)

It's still important to group

• a document
• and its relationship with
• another document

together and test them as a whole for each assertion in the test.

All that was needed was to

1. revert 6e4c803, and
2. add html=True to each of the self.assertContains calls

Edit: See the official documentation on assertContains below.

https://docs.djangoproject.com/en/4.2/topics/testing/tools/#django.test.SimpleTestCase.assertContains

Set html to True to handle text as HTML. The comparison with the response content will be based on HTML semantics instead of character-by-character equality. Whitespace is ignored in most cases, attribute ordering is not significant. See assertHTMLEqual() for more details.

The test failing above appears to be unrelated to this PR.

Also, I could not reproduce it locally.

ietf/manage.py test --settings=settings_test

Ran 1547 tests in 1420.206s

OK

The job was re-run but failed again. https://github.com/ietf-tools/datatracker/actions/runs/10802493115/job/29971686883?pr=7921#step:6:1896

On the third attempt, all tests successfully passed. https://github.com/ietf-tools/datatracker/actions/runs/10802493127/job/29964665583?pr=7921

I'll create an issue re: reproducible tests unless there's one already.
