fix: "Course Number Display String" option doesn't influence certificate

[DmytroAlipov]

Description

In Advanced Settings, it is possible to redefine the name for the Course Organization as well as for the Course Number. However, a bug was discovered in replacing this name on the certificate:

For Course Number Display String everything works correctly:

But the name of the organization is always taken from the Organizations model. In this case, the definition from Advanced Settings is ignored:

For other pages, the override works correctly for both settings:

I slightly changed the logic for prioritizing the selection of the organization name for the certificate. Now everything is replaced correctly:

Hi @DmytroAlipov,

I was just taking a look at these changes this morning and it's a good catch. Are there any tests that can be added or updated?

[DmytroAlipov]

Hi @justinhynes The testing situation here is difficult since the _update_organization_context function is difficult to test. This needs to be tested in the render_html_view context. There are no testing examples for this at the moment. I'm unlikely to be able to test it correctly. Can someone on your side help with this?

[justinhynes]

OK! Thanks for the heads up. I'm not very familiar (personally) with the test suites around this functionality, I'll try take a look this morning. Worst case, we toss a story in our backlog to take a deeper look at improving test coverage in the future.
