Update check_resource decorator to account for new resource names

Fixes #1639

@shin- connect_container_to_network() and disconnect_container_from_network() check 'image' as resource ID. Shouldn't these check 'container' instead?

[shin-]

@matthewtberry They certainly do. Can you create an issue / submit a PR? Thanks!

[matthewtberry]

@shin- Yeah I can do both! Thanks.

Actually, this fixes APIClient.inspect_node, which has been unusable from 1.10.0 on until 2.4.0 (when this fix has been first included) because it always errored with image or container param is undefined.
