remove duplication of all jest configs (Kong#3375)

* use jest-preset for all but app

* separate properties that are the same as the preset

for some reason, it doesn't work.  you get:
```
Preset ../../jest-preset.js not found.
```

This needs to be investigated.

* removes unused/unneeded npm script in `app`, `test:jest`

jest.config.js → jest-preset.js
