openvino/workbench 2022.1 always defaults to Device=CPU in the first run

[dnoliver]

To reproduce:

1. Launch workbench, and use "Erase All"
2. Import a model (IR is faster)
3. Select an environment, and choose a non-CPU device (e.g. GPU, MYRIAD, HDDL), verify that the device is selected in the "Select Environment" section
4. Select a validation dataset, import the default one
5. Once the UI goes back to "Create Project", the Device property in "Select Environment" is reverted to CPU

Expected Result: non-CPU device selection should be persisted
Actual Result: workbench defaults to CPU

If you run the project, it runs on the CPU.
This only happens on the first time you start workbench, or after an Erase All. Further executions works as expected

Screenshot 1 shows the selection of MYRIAD:

Screenshot 2 shows the project executed with CPU, even when MYRIAD was selected
