Setting visibility="submission" results in the submission field being hidden

[tdonohue]

Describe the bug If you attempt to sent any submission field to "submission" visibility, it will be entirely hidden in the submission form.

To Reproduce Steps to reproduce the behavior:

1. Define any field as submission-only (<visibility>submission</visibility>) in your submission-forms.xml. For example:

         <row>
              <field>
                  <dc-schema>dc</dc-schema>
                  <dc-element>title</dc-element>
                  <dc-qualifier>alternative</dc-qualifier>
                  <repeatable>true</repeatable>
                  <label>Other Titles</label>
                  <input-type>onebox</input-type>
                  <hint>If the item has any alternative titles, please enter them here.</hint>
                  <required></required>
                  <visibility>submission</visibility>
              </field>
          </row>

2. Submit a new Item which uses that form. That field will not be visible in the submission form.
   • NOTE: If you submit the Item and it goes into workflow, that field will also not be visible in workflow.

Expected behavior Fields which have <visibility>submission</visibility> should APPEAR in the submission form, but NOT APPEAR when the item is in workflow approval.
