Can't change nodes when trying to run a saved job

• Issue Type: Bug
• Rundeck version: 1.4.2

Issue:
" When trying to run a saved Job, there's the "Nodes" section, and a checkbox for "Change the Target Nodes", and a "Matched Nodes" rollup. If you expand "Matched Nodes", you see the matched nodes with greyed out checkboxes that cant be changed, and checking "Change the Target Nodes" doesn't change anything.

I would expect to be able to deselect existing matched nodes, and by checking "change", change the filter for nodes, but neither appears to be the case.

If you check "Change" and the "Run Jobs Now" button, you get a running job status screen that reports "failed" and has the one output line:

Step 1 of the workflow threw an exception: No nodes matched,Caused by: No nodes matched

Reproduce:

1) Select a saved job
2) Expand the "Matched Nodes" section, see that the checkboxes are greyed out.
3) Click to mark "Change the Target Nodes", note that the matched nodes checkboxes don't change
4) Click the "Run Jobs Now", see the error on the resulting page.
