At some point settings DSL was refactored to first add a preference and
then run the builder. We shouldn't add a preference to the hierarchy
without setting a key for the preference first because preference gets
it's default value in `onAttachedToHierarchy()` and if the key is not
set then no default value will be set either.
This commit changes the order to execute builder (and set the key)
first and and preference to the point later.
* Refactor main preferences to use DSL
* Refactor account preferences to use DSL
* Use DSL in rest of the preference screens
* Preferences cleanup
* Fix preference dependencies
