[clangd] Fix broken build after r351793.

LGTM, but hokein might know better whether to push the default options or the one in ClangdServerOpts

I'm going to land this now to unbreak build. Feel free to comment or do further refactoring if the default is not the best thing to pass here. Currently, this doesn't seem to matter as it's not used in CodeCompletion.

nvm, Simon beat me to it ;)

I think it is safe to use the empty one (constructed by the default constructor) here -- since getDefaults is not free, and we don't need the configurations in codeComplete, fixed in rL351826.
