Instead of returning an empty array in prepareTypeHierarchy, sourcekit-lsp should return nil#1178

…kit-lsp should return `nil` Eg. when requesting type hierarchy of a class when the project hasn’t been built, sourcekit-lsp returns an empty array. That causes VS Code to fail with very ambiguous error messages - MISSING provider - Cannot read properties of null (reading 'kind') To work around this, instead of returning an empty array, return `nil` instead. rdar://126228814

I assume this is because it always expects at least the original element itself? Does call hierarchy have the same issue?

Call hierarchy doesn’t seem to have that issue.
