The "tags" in a CompletionItem response should be an array, not null

[rwols]

I'm noticing that the "tags" of a completion item is null, but this violates the spec. You should leave the key out altogether if there are no tags.

I think this just needs to be marked optional:

this is really a bug in csharp-language-server-protocol I think. cc @david-driscoll

This is fixed. Automation will rev the version of the library that we use and it'll be in the next version of PSES
