python_keywords: Change parsing container ID from a given CLI output

The stdout in the neofs-cli was changed, so parsing container ID has been fixed
in the tests.

Old format:
container ID: 2tz86kVTDpJxWHrhw3h6PbKMwkLtBEwoqhHQCKTre1FN
awaiting...
container has been persisted on sidechain

New format:
container creation request accepted for processing (the operation may not be completed yet)
container ID: 2tz86kVTDpJxWHrhw3h6PbKMwkLtBEwoqhHQCKTre1FN
awaiting...
container has been persisted on sidechain
