LSP: CompletionRequest: set triggerCharacter when possible

Browse Source 
When the completion request is triggered by an activation character,
set the triggerCharacter accordingly.
This can help the language server to propose more sensible items.

Detected while trying cmake language server. It was throwing an error
when triggerKind is TriggerCharacter and triggerCharacter is not present.
