Fix incomplete help text for encrypted & unencrypted subcommands

Subcommands of the encrypted and unencrypted commands were found to have
a wrong help text displayed. The reason for that behavior was that the
subargs were are constructing as part of the argument parsing process
were missing the command being requested and instead containing only the
subcommand.
This change fixes this deficiency. It also adds a test ensuring that the
"Usage" string displayed in the help text of each command and subcommand
contains the proper arguments.
