Invocation forwarders currently cannot distinguish a named parameter not passed from passed as `null`. Refactor `getNamedParameter` to return nullable index. When the index is not null it means that the named parameter is present, and its value may be `null`. This doesn't fix any of the existing tests so I added a regression test.
