tsconfig for app project

Description

There should be a different tsconfig for the app, that uses TypeScript 3.2.4 and can't be upgraded at the moment. node_modules/@openstapps/configuration/tsconfig.json(8,5): error TS5023: Unknown compiler option 'incremental'.

Explanation

The App Project uses an older typescript version. That does not support the "incremental" flag.
