openvino/workbench 2022.1 fails to cleanup environments folder

[Nicolas Oliver]

To reproduce:

1. Start workbench
2. import and convert a model
3. Use "Erase All"

Expected: .workbench/assets/environments should be empty
Actual: generated environments are present after cleanup

After several executions of step 2 and 3, the environments folders gets big enough to cause delays in container startup:

$ du -sh .workbench/assets/environments/*
1.1G    .workbench/assets/environments/1
1.1G    .workbench/assets/environments/2
