Smoke test other tabs.

Now that #38 is merged, I'm reminded that I wanted to check all pages load without error.
🥁 ...... they don't.

Not sure if this behaviour is expected/intended (in which case we shouldn't test for error-free loading). But perhaps it should be possible to startwazp → not load anything → and just click around the (empty) tabs. What do you think?

To run locally

• Same instructions as Integration testing mechanics. #36 (need chromedriver in your PATH).
• Screenshots of the pages where there were errors in loading are saved in .test_fail_screenshots.
  • They look OK to me, so tentatively: do we just silence these loading errors?

Closed in favour of #82
