Issue Summary

When moving a child issue into a new project, and setting the issue type on the moved issue to Epic, the parent link to the original Epic breaks.

Steps to Reproduce

1. Create Epic Issue 1 in Project A
2. Create child issue Issue 2 as non-epic issue type
3. On Issue 2, begin Move operation
4. Move issue 2 to Project B and change issue type to Epic
5. Issue 2 will now be an Epic with no parent visible in Breadcrumb and no issue links

Expected Results

Issue 2 exists in Project B and either has no issue links, or a way to remove the parent link to Issue 1

Actual Results

Issue 2 has no visible issue links, but Issue 1 still links to Issue 2 as a child. There is no visible way to remove this issue link from either Issue 1 or Issue 2.

Workaround

Changing the issue type on Issue 2 will remove all parent link associations. This will also remove any child issues of Issue 2, which must then be manually reassociated with it.
