network ls: handle removed container

Handle a race condition in the REST API when listing networks. In between listing all containers and inspecting them, they may have already been removed, so handle this case gracefully. [NO NEW TESTS NEEDED] as it's a race condition. Fixes: containers#17341 Signed-off-by: Valentin Rothberg <[email protected]>
