Tweak AbstractMatcherTestChecker

[Stephan202]

Suggested commit message:

Tweak `AbstractMatcherTestChecker` (#2050)

Refaster template parameters will never match only the identifier of a
method's receiver parameter, so for the purpose of testing `@Matches`
and `@NotMatches` predicate classes, there's no need to descend into
`VariableTree#getNameExpression()`.

See https://docs.oracle.com/javase/specs/jls/se21/html/jls-8.html#jls-8.4

@rickie we discussed this offline. I don't think this is relevant to #261, though.
