Fully automate the test: zarhus-base/02_cog_memory_leaks.robot

[artur-rs]

The problem you're addressing (if any)

Changes introduces here: e4bbd9c still require manual steps to run the full test suite.

Describe the solution you'd like

Running test-suite command from CLI should be the last step to get test results. We should not rely on the tester, who needs to check what should be done manually and confirm the steps by Enter/Return key.

Where is the value to a user, and who might that user be?

User/tester who wants to prepare a full test report for the product: [02Y] WebKit Service Stability Tests

Describe alternatives you've considered

To fully automate the tasks, maybe it is required to prepare the firmware/platform in case of the problem mentioned here: #421 (comment)
