Fix containers list/prune http api filter behaviour

Browse Source 
The problem described in #9711 and followed by #9758 affects
containers as well. When user provides wrong filter input, error
message should occur, not fallback to full list/prune command.
This change fixes the issue. Additionally, there are error message
fixes for docker http api compat.
