[PATCH] Revert "Allow assigning of any user as delegate"

[Stephen Finucane]

From: Stephen Finucane <stephenfinucane at hotmail.com>

This reverts commit e0fd7cd91a5fbe0a0077c46bea870ccd09c8920d.

This change does not scale with a larger number of lists, and clearly
needs more work. Revert until such a time as this is carried out.
