* 3 more fixes for TS 3.7

lyricist: patch tests until TS fixes Promise.all
react-relay: fix lint
react-sortable-tree: upgrade react-dnd dependency

The change to lyricist is just a workaround for now.

React-sortable-tree's upgrade is the same as other dependents of
react-dnd that I did yesterday.

* More compatible workaround for lyricist
