Original change's description:
> [AF][Paradise] Enable Paradise settings button for non-sync users
>
> Previously there were two sets of prerequisites checks which are fragile
> and complex. Here I refactored the LocalCardMigrationManager to allow
> prerequisites checks to be shared by both checkout form flow and
> settings page flow.
>
> Change in the LocalCardMigrationManager is already covered by unittests
> and browsertests. So I only modify the test file for payments_section.js
