rename tests to not contain the word "fail"
When I look at the test results (in the web page), the first thing thing I do is CTRL-F "fail". That finds a lot of irrelevant occurrences, because the term "fail" is part of the names of tests. That is annoying. Rename those tests. Yes, I know that all the names here are lower case "fail", while I'd need to search for "Fail" case-sensitive. Still, let's avoid that and rename the tests. Some tests were renamed entirely to avoid the term "fail". Other tests, got a name with the intentional misspelling "faiil".
Result: UNSTABLE: Some tests failing
Passed: 455, Failed: 2, Skipped: 36
