Action: remove-purchase doesn't handle the case of Quick Start Session.

This issue is just for leaving a note here. Currently there is a bug causing the subscription removing button to be missing sometimes. We should fix that instead of making this action smarter.

No file, test, or entry point is named. Start by reproducing the missing subscription removal button during a Quick Start Session and trace the remove-purchase action's behavior. Done means fixing the underlying button-visibility bug rather than making the action smarter.
