WC Follow-ups 'Last status' not working

[Valentina R]

For Appointment emails, the ‘Last Status’ cannot be set to anything other than ‘Any status’.

To reproduce, save ‘last status' value as ‘unpaid’. Page reloads and it says ‘unpaid’. But if you reload the page youl see it goes to ‘any status’.

Reported here.

Fixed with 4.9.5.

Last status should be used in rare occasions when you want to check the status transition and build notification on that. For instance, when appointment goes from Unpaid to Paid, last status should be set as Unpaid. Statuses inside triggers should be used in most cases.
