Moved check for self.has_capability("diagnosticProvider") to the top which changed indentation quite a bit and made it harder to review. Enable "hide whitespace changes" to make it easier to read.

Apart from that, added a check and bail for the case when requesting diagnostics for document version for which there already is a pending request. Without the added check it would cancel existing and trigger a new one which is a waste if the document hasn't changed since.
