configs.__newindex(): set init_options to empty dict

Problem:  Sending default initOptions to ra_lsp_server the init options
          emits error: "failed to deserialize config: invalid length 0,
          expected struct ServerConfig with 12 elements" when receiving
          an empty initializationOptions from vim.lsp.
Solution: Use an empty dict instead of empty list for
          default_config.init_options

LSP spec says initOptions must be a dictionary.

fix #94
fix #107
