The definition of Preconditions and links associated are removed when moving the Xray issue

Short Description: The definition of Preconditions and links associated are removed when moving the Xray issue to another project.

Steps to Reproduce:

1 - Create a Test.

2 - Associate a Precondition to it.

3 - Open the Precondition and write a definition.

4 - Now, move the Precondition to another project.

5 - Navigate to the Precondition page.

Actual Results: The Precondition no longer has a definition and the link between precondition and test does not exist.

Expected Results: The Precondition should keep its definition and the link between precondition and test.

6 - Now, create a Test of a kind X in project A.

7 - Associate a Precondition to it and write a content on it.

8 - Move the Test to another project B that does not have the kind of the Test of project A.

9 - Navigate to the Test.

Actual Results: The Test will have another kind, but the link between the Precondition and Test still exist.

Expected Results: The link between the Precondition and the Test should not exist because the Precondition is still the previous one and the its Kind does not match the new one of the Test.
