For each rule, added a non-identity transformation test case, to validate that the @Matcher annotation is present.

Previously we would only match Function.identity(). Our internal code base contains a number of UnaryOperator.identity() usages that were thus not matched by the Refaster rules.

Want to add something to the commit message? Something like While there, generalized Refaster rules using this matcher.?

Good point @rickie. How about (slightly tweaked):

Introduce `IsIdentityOperation` matcher for use by Refaster templates (#749)

While there, generalize a number of Refaster rules using this new matcher.
