It's not possible to create linked issue from an SD project to another without Agent access on both projects

Problem

It's not possible to create linked issue using the Create Linked Issue function from a Service Desk project to another if the user is not an Agent of both projects.

Steps to reproduce the issue

1. Create a user with application access to Service Desk.
2. Create 2 Service Desk projects which share the same permission scheme.
3. Grant the user with the Service Desk Agent permission of one of the projects (project A). In the other project (project B), grant only Browse Projects, Create Issues and Link Issues permissions to the user.
   • This means that the user is an Agent of project A but not an Agent in project B.
4. As an Agent of the Service Desk project, use the Create Linked Issue option to create a linked issue in the other Service Desk project (project B) which the user is not an Agent.

Expected result

The Create Linked Issue operation can be completed without any error on the screen i.e. the issue is created and linked on the fly.

Actual result

1. On the Create Linked Issue screen, an error You do not have permission to link issues in this project appears and the operation cannot be completed.
2. Even though with the Create Issues and Link Issues permissions in the targeted project, the Agent will not be able to create the linked issue. However, the create issue and link issue operations can be performed separately.
