> In the code below ideally we'd expect a SINGLE ROW DELETE plan client side. However,
this generates an incorrect scan with range ['tenant1    0CY005xx000001Sv6o'). If the
order of the RVCs is changed to row key order Phoenix correctly generates a SINGLE ROW SCAN. 
As we provide the full PK this we expect a either tightly bounded range scan or a client side
delete.  Instead we get a range scan on composite leading edge TENANT_ID,KEY_PREFIX,ID1.
