libpod: unset networks before storing container conf
Since networks must always be read from the db bucket directly we should unset them in config to avoid caller from accidentally using them. I already tried this but it didn't work because the networks were unset after the config was marshalled. [NO NEW TESTS NEEDED] Signed-off-by: Paul Holzinger <pholzing@redhat.com>
