Muir Manders 5bf02b21f1 internal/lsp/source: fix bug in deep completion score tracking
We keep track of the N highest seen scores so we can quickly skip deep
completions not in the top N. Our logic for maintaining the top N list
wasn't quite right, resulting in certain cases where we would let
non-high scoring candidates through. I don't think the bug impacted
correctness.
