WHAT
At the moment the logic randomly selects a system-developer and system-provider tenant route to test for availability.
If a route selected is related to an account/tenant that is scheduled for deletion, this will result in a 404. See attached.

HOW
Add some intelligence to how we select a system-developer and system-provider route.
At least, ensure that the account is not scheduled for deletion.

Potentially use porta client and hit api to get accounts in the middle state, "approved" 

TESTS
Create an account/tenant and delete it.
Create a new account
Ensure alert does not fire.
