non existent permissions that are linkauthed to are not reported in get_account's linked_actions

linked actions probably iterates through the account's permissions, thus it wouldn't look for linkauths for a permission it doesn't have. There is also some question as to whether a similar issue might arise when a permission delegates to some other permission, whether it recurses.

Need to investigate the implications of this, and also whether we even have the right data indexed to be able to improve on this.

After activation of ONLY_LINK_TO_EXISTING_PERMISSION which occurred Sep 2019 it is no longer possible to linkauth to a non-existant permission. And it was never possible to remove a permission that was linkauthed to. Issue was reported on an account that created a linkauth prior to Sep 2019.

Create unit test to ensure expected behavior doesn't regress, then close.
