Remove some *indirect* loops in the BasePreferences.getAll-method

Browse Source 
In the `getAll`-method, we can have just one *explicit* loop rather than two indirect ones via the old `Object.assign`-call.

Also, changes the `get`-method to be slightly more compact (while keeping the logic intact).
