patch 9.1.1049: insert-completed items are always sorted

Problem:  insert-completed items are always sorted, although the LSP
          spec[1] standard defines sortText in the returned
          completionitem list. This means that the server has sorted the
          results. When fuzzy is enabled, this will break the server's
          sorting results.
Solution: disable sorting of candidates when "nosort" is set in
          'completeopt'
