subtests...restart: cleanup() rm failure bug.

Cleanup can ignore status of rm, relying on env check
to pick up non-removed containers.  Otherwise it will
fail the test if container doesn't exist.

dockertest.images: Support 'None' value images

There's no practical reason why images w/o names but with
valid Id's should be treated specially.  It's a perfectly
acceptable intermediate state, but should not persist.
Added a test in env checks to verify this.

dockertest.images: Qualify nakid exception

A nakid ``except`` clause in the images module was hiding
the cause of a failure in the rmi test.  The most likely
exception to be thrown is a ``TypeError``, and so it was
specified.

dockertest.subtests: Ignore empty/missing log args

Subtests.log_xn annoyingly complaining about multi-line
messages that don't have any arguments.  Since this is
a perfectly valid usage, the method needs to test the
contents of args, and simply ignore it when empty.  If
it's a problem, it will be obvious by the '%X' (tokens)
appearing in the output, no need to fail a test for this.

subtests...rmi: --run marked as deprecated

Docker client version 1.1.1 reports the --run argument to
the commit subcommand is deprecated.  Added version-check
to bypass processing this parameter in rmi test.
