Compat with node 14

[bdombro]

bootstrap is failing for me on node 14 at the db:create step, whereas it works in node < 14. Not really sure what's going on but could look if you'd like.

I tracked this down to an issue with TypeORM in Node 14 I think. For now, I think it makes sense to update package.json engines to specify <14. In parallel, could bump the TypeORM version and see if it would work on 14.
