LSP: Fix option handling in goto definition/references commands

Browse source 
The language server may return `None` for a definition/reference
request. The parent commits introduced a regression for these commands
when a server did not provide locations. With this change a server may
respond with `null` and its locations will instead not be considered.

Fixes #12732
