Ben Langmuir 8c0d5408b7 [CodeCompletion] Fix call-arg completion when we remove all the overloads we found ...

We have code for pruning unlikely overloads, but when it pruned all
overloads it was treating that as if there was nothing to complete.
Instead, fallback to postfix-expr-begin.

We should also figure out why we're not getting any viable types here,
but we need to handle failure gracefully.
