Description of problem:

When using the Use Legacy Form for a remote execution task, the Schedule Future execution radio button only works for the default Job Category: Commands and Job Template: Run Command - Script Default.

If you change the Job Category and Job Template, the Schedule Future execution radio button is still there, but if you click on it, nothing pops up under it to configure the Start at or Start before parameters.
 

How reproducible:
Always
 

Is this issue a regression from an earlier version:
Yes, this was working in Satellite 6.15. In Satellite 6.16 and 6.17 this functionality stopped working.
 

Steps to Reproduce:

1. Navigate to Hosts => All Hosts

2. Toggle the box next to a host.

3. Select the Schedule Remote Job from the Select Action drop down menu.

4. Change the Job Template and Job Category, e.g. Katello and Install Errata - Katello Script Default

5. Select the Schedule future execution radio button

Actual behavior:
[Describe the issue in detail, including what is happening and where]
Nothing pops up under the Schedule future execution button. The user should be prompted with 2 additional parameters, Start at and Start before.

Expected behavior:
[Describe what should be happening instead]
The 2 parameters Start at and Start before should pop up under the Schedule future execution radio button.

Business Impact / Additional info:
Only affects scheduling tasks in the future for the legacy UI. The new UI works, but the legacy UI is easier / more convenient for the customer to use.
