Tried to snapshot save an app, but messages returns a restore instruction.

Expected results:
Now that 'rhc app snapshot' is an alias of 'rhc snapshot', it should run successfully.

Additional info:
Both the following command syntaxs failed 
rhc app snapshot save -a app1 -f app1.tar.gz
rhc app snapshot save app1 -f app1.tar.gz

Same problems also happened with 'rhc app snapshot restore'
