Organization Field can be set to Required in Create Screen

Summary

Currently, the 'Organization' field in Service Desk can be set as a required field and added to the 'Create' screen for an issue. The problem with this is that the 'Organization' selection only shows up in the Customer Portal and will not appear as a visible field in the Create screen, thus making it impossible for an admin to require an organization to be chosen, and create a Service Desk ticket through JIRA rather than the Portal. 

Steps to Reproduce

1. Set 'Organization' as a required field

2. Add the field to the create screen in a Service Desk project

Expected Results

The field should be visible and able to be set, or Service Desk should not allow you to set the field as required. 

Actual Results

The field will only be visible in the Customer Portal and a user will not be able to create a ticket in that project through JIRA.

Notes 

This might be intended functionality (as Organization is primarily a contact field and is meant as an option for customers to share a ticket with their org.), but allowing it to be set as required and put into a 'Create' screen causes confusion, as the ability implies that this field can be set through JIRA during issue creation.
