clearFWStep step in tests not clearing states

[ol-imorozko]

Steps to reproduce

• Compile autotests
• Modify autotest.yaml in 045_firewall_out test (sleep 10 to be sure)

diff --git a/autotest/units/001_one_port/045_firewall_out/autotest.yaml b/autotest/units/001_one_port/045_firewall_out/autotest.yaml

• Run ./autotest/yanet-autotest-run.py --prefix=build_autotest autotest/units/001_one_port autotest/units/001_one_port/045_firewall_out/

Expected result

clearFWState should clear states and we should see no entries in yanet-cli fw list states
