Cannot use namespace 'Knex' as a type

See original GitHub issue

Steps to reproduce

Generated a clean app with TypeScript enabled feathers generate app
Generate a new service with feathers generate service and choose KnexJS as service type

Expected behavior

When starting the app (nom start) tsc should compile successfully.

Actual behavior

Lots of errors about Knex namespace. E.g:

node_modules/feathers-knex/types/index.d.ts:22:10 - error TS2709: Cannot use namespace 'Knex' as a type.

22   Model: Knex;
            ~~~~

src/models/users.model.ts:8:45 - error TS2709: Cannot use namespace 'Knex' as a type.

8 export default function (app: Application): Knex {
                                              ~~~~

I had the same issue using the Objection driver which also utilises Knex. To fix it you should just need to change the import statement in src/models/users.model.ts from import Knex from 'knex'; to import {Knex} from 'knex';.

Of course this doesn’t change whats created via the CLI but should allow it all to compile in the meantime.
