ATOS says it is ARMED but when pressing start, says not all objects are ARMED

[Angeleon]

Describe the bug
Occasionally when running a scenario with more than 1 testobject, the state is reported as "ARMED", but when clicking on "Start" it reports "Not all objects are in state ARMED" (Not exact phrase). This has been found when ATOS is running a simulation, but there should be nothing in this that is simulation specific.

Rate of occurance: 2/30 times or so.

To Reproduce
Steps to reproduce the behavior:
Run a scenario with more than one TestObject
Initiate
Connect
Arm
Start

Sometimes this issue will occur.

Expected behavior
If ATOS shows state ARMED, all objects should be ARMED as well.

Branch or release information (please complete the following information):

• Branch/release name: feature_simulationController, but should be present in dev and main as well.
