Spies for property accessors are not automatically cleaned up

[Carl-Erik Kopseng]

Describe the bug
If we use Sinon to spy on property accessors, these spies are not cleaned up (restored) when restoring the sandbox.

To Reproduce
Steps to reproduce the behavior:

const executeInsertSpy = sinon.spy(o, "executeInsert", ["get"]);
o.executeInsert
o.executeInsert
assert.equals(executeInsertSpy, 2);
sinon.restore();
executeInsertSpy.get.restore(); // We should not be able to or be required to do this. BUG!

Expected behavior
All spies are cleaned up

Context (please complete the following information):
