Fix flaky point series test.

[lukeelmers]

Attempts to fix this flaky test: #27905

I have been unable to reproduce this failure locally, making the problem particularly difficult to diagnose. Tried throttling my network speed and rerunning a number of times, and it still passes consistently.

Once thing I did notice was that in other tests where we are saving a visualization, we tend to use waitForVisualizationSavedToastGone() after saveVisualizationExpectSuccess(). So I added that here in case the vis is trying to load too soon. Will try rerunning CI several times to see if this is actually helping.

@lukeelmers - I commented on the issue, I think this might fix it, but as a by product of the extra wait time for the toast to be gone. What do you think of first trying clickByCssSelectorWhenNotDisabled and adding in a expectToBeOnLandingPage check. If that doesn't fix the issue we can try something else, but I think the fix should be inside visualize_page.js so all callers will get the fix.

Last build failed on "

I am investigating a fix, though am out today and tomorrow so won't be able to make much progress on it. I think some of the checks need to be wrapped in a retry for the pie chart because it takes the filters a bit to refresh/reload (pie chart doesn't emit "render-complete" correctly so we can't rely on that).
