This change cleans up internal/lsp/source/view.go to have a more logical ordering and deletes the view.CheckPackageHandle function. Now, the only way to get a CheckPackageHandle is through a snapshot (so all of the corresponding edits). Also, renamed fuzzy tests to fuzzymatch. Noticed this weird error when debugging - I had golang.org/x/tools/internal/lsp/fuzzy in my module cache and it conflicted with the test version.
