EFM - Crossed commands creates unarrestable acceleration towards ground

[psimo46]

-- EFM branch --

How to reproduce:

• Level flight
• Go Idle
• When approaching stall speed initiate spin induction maneuvre (stick full aft and to one side, rudder to the other) and keep it

Actual result: The aircraft enters a stall state apparently unarrestable, accelerating further than 300 kts CAS

Expected result: Entering a spin, or at least a stall state with a terminal velocity
