Fix issues with object related commands

1) Can't create instance of swiftclient. Since we now create
an API instance, creating a swiftclient instance won't work.
Trying to do any object related command fails.

2) Listing objects in a container fails, we depend on the
data returned in a specific way, during the API transition
this must have slipped through.

Needs regression/funcitonal tests to mame sure this doesn't
happen again.
