Fix: ExampleLastInsertId() -> ExampleResult_LastInsertId()

The new tests analyzer reports common mistakes in declarations of
tests, fuzzers, benchmarks, and examples in test packages, such as
malformed names, incorrect signatures, or examples that document
non-existent identifiers. Some of these mistakes may cause tests
not to run. This analyzer is among the subset of analyzers that
are run by go test.
