Description

Hopefully the title makes sense.

Repro steps:

Create Issue 1
Create Issue 2 and assign 1 as parent
Create Issue 3 and assign 1 as parent
Navigate to issue 3 and assign 2 as parent
Navigate to issue 3 and re-assign 1 as parent

Step 5 will display "Parent Task is invalid".

Workaround:
5. Navigate to issue 3 and remove any parenting
6. Navigate to issue 3 and re-assign 1 as the parent

Seems the issue can't be assigned to its parent because it would create a conflict reassigning the lft and rgt fields of the 3 issues involved.
