relay-store: Enabling TSLint strict flag results in type errors

[olerichter00]

Hi @morrys ! 👋

Firstly, thanks for your amazing work! 🙂

We are using @wora/relay-store 6.0.0 in our project Eigen and ran into a type issue with strict mode enabled.

I've create a PR to fix the type issues we encountered and here is the diff that solved my problem (from patch-package):

TSConfig Error Message:

node_modules/@wora/relay-store/lib/RecordSource.d.ts:22:5 - error TS2416: Property 'toJSON' in type 'RecordSource' is not assignable to the same property in base type 'IMutableRecordSourceOffline'.
  Type '() => RecordMap' is not assignable to type '() => { [key: string]: Record<{}>; }'.
    Type 'RecordMap' is not assignable to type '{ [key: string]: Record<{}>; }'.
      'string' index signatures are incompatible.
        Type 'Record<{}> | null | undefined' is not assignable to type 'Record<{}>'.
          Type 'undefined' is not assignable to type 'Record<{}>'.
