rd keys list NullPointerException when no keys are present

[xirixiz]

"rd keys list" gives a NullPointerException when no keys are present in Rundeck.
It would be nice to receive a message that currently no resources are configured, or something like that.

[gschueler]

can you paste the stacktrace?
