pw usermod: Properly deal with empty secondary group lists (-G '')
"pw usermod someuser -G ''" is supposed make sure that someuser
doesn't have any secondary group memberships.
Previouly it was a nop because split_groups() only intitialised
"groups" if at least one group was specified. As a result the
existing secondary group memberships were kept.
