Tests: remove unnecessary trailing spaces from the test files

While adding a new test to `CapitalPDangitUnitTest.1.inc`, I noticed unnecessary trailing spaces in this file. Instead of removing them just for this one test, I opted to create this commit removing unnecessary trailing spaces from all test files using `Squiz.WhiteSpace.SuperfluousWhitespace`. I'm including only the files where it was easy to check that the spaces were not added intentionally.
