    vls: bind LSP client lazily for search
    
    This ensures that the client is not spawned unless another component has
    caused it to.
    
    That does have the side-effect of requiring the user to actually open
    something that requires vala before search results are displayed. Not the
    end of the world, but in the future it might be nicer to sniff this out.
    
    Fixes #1476
