Properly expand the environment's name in all commands

Since 3777701f, the environment's name is
automatically expanded in console and dbconsole commands.
In order to match the behavior between the commands, fixes it to have the
same behavior of all the commands.

This behavior is defined in `EnvironmentArgument`. Since
`EnvironmentArgument` also defines the environment option, it is reused.

However, since desc was not content that can be used in all comments,
fixed desc to be defined for each command.
