Rename test classes from Test* to *Test (#1359)

Since class names are usually nouns, test classes should be named like
`ClassNameTest` instead of `TestClassName`.

This convention is now commonly used in projects (e.g. Rails) and tools
like Ruby LSP use it to check if a class is a test class. (From tools'
perspective, checking `Test` as a postfix is more accurate than checking
`Test` as a prefix as `TestHelper`, `TestCase`...etc. are not test
classes.)

I've previously renamed some classes this way. This commit renames all
remaining classes to follow the convention.
