User should be able to remove the field from Request Type page even if it's marked as required

On the "Request types" page, if a field is marked as required it is not possible to remove it.

Steps to reproduce

1. On a JSM project settings > Request types > click "Edit fields" on a request type
2. Add a field
3. Mark it as Required = Yes

Observed Results

On the actions column, the "Remove" link is grayed out and it displays a confused message "This field is required by the linked issue type"

Expected Results

The "Remove" link should be enabled as I don't see a valid reason of why the user should not be able remove the field only because the Required column is set to "Yes".
