JSON format includes description for project list

Bug report

This may not be a bug but a functionality issue.

When invoking the command projects from the rd utility with RD_FORMAT=json the project name and project description are concatenated. Trying using -v option won't work. One should expect to receive a JSON object with not mixed values.

My Rundeck detail

• Rundeck version: 2.7.1 and rundeck-cli-1.0.5-1
• install type: rpm
• OS Name/version: RHEL 7

Expected Behavior

It's expected to receive as output project names, like the following:

$ RD_FORMAT=json rd projects
[ "ProjectA", "ProjectB", "ProjectC" ] 

or in the best case:

$ RD_FORMAT=json rd projects -v
[
   { "name": "ProjectA", "description": "ProjectA description" },
   { "name": "ProjectB", "description": "ProjectB description" },
   { "name": "ProjectC", "description": "ProjectC description" },
]

Actual Behavior

Each element of the array is being concatenated with project description, just like:

$ RD_FORMAT=json rd projects
[ "ProjectA: ProjectA description", "ProjectB: ProjectB description", "ProjectC: ProjectC description" ]

How to reproduce Behavior

Run rd projects

It should allow the -%/--outformat flag for text output, and default to more sensible json output
