Always return json object from module commands

Browse Source 
If a module command returns a json object, it will always be
returned to the caller, irrespective of whether the command
itself succeeded or not.

Otherwise, if the command failed and if the module command has
set an error message, that error message will be returned as a
json object containing the error message.
