.catch should not trigger on a command group

when not implementing a catch hook, typing in a command of a group gives you the help for it's subcommands.

if however you implement a catch hook, the catch hook is triggered instead.

I think it would still be useful to show the help for a command group, instead of triggering the catch.

Ah good point. Agreed.

do the catch and show the help:

.catch(function(err){

})
.then(function(){
  // show the help
})

?
