fix(semantic_tokens.lua): Fix nil tokens/data in semantic_tokens.luafix_semantic_tokens_pull
Some (poorly-implemented) LSPs can return an empty JSON object in LSP responses, which could cause tokens to be nil, which would eventually cause an error and a bad UI experience. This fix makes sure that the tokens variable is always set to a non-nil value.
