bb forms export error message instead of options for this command

[rodrigoschaves]

Behaviour
When you try to run "bb forms export" :
Unhandled rejection Error: connect ECONNREFUSED 127.0.0.1:8093
at Object.exports._errnoException (util.js:870:11)
at exports._exceptionWithHostPort (util.js:893:20)
at TCPConnectWrap.afterConnect as oncomplete

Expected, show the help with the possible options:
Options: -short, --name default description
-sH, --studio http://admin:welcome@localhost:8093/ Studio host.
-r, --repository Repository from which to export the project.
-b, --branch Branch name of the version to export.
-p, --project Name of the project to export.
