968521c6 - [Completion] Fix trailing closure index check

[Completion] Fix trailing closure index check `Res.FirstTrailingClosureIndex` is an index into the argument list, so comparing it against a parameter index is wrong. Instead, compare it against the argument index of the completion token, which is what we want to be checking. This ensures we don't try and offer argument completions for non-function default arguments. rdar://127760308
