Rename getAnExpectation to hasExpectation

`getAnExpectation` is a relation that holds between an expectation comment
and the parsed parts it carries, not a function returning a single value,
so the `get` prefix is misleading and trips the CodeQL predicate-naming
style check. Rename it to `hasExpectation`, matching the `has`-prefixed
convention for such predicates (and the sibling `hasExpectationWithValue`).

Pure rename with no behavior change; reformatted with `codeql query format`.
