Fix error logging of master/minion ingresses

[Dean-Coakley]

Bug

Under certain conditions of invalid minions/master ingress the entire struct is logged out instead of just the name.

Case1.

• Minons present with no master deployed

Case2.

• Master in an undesirable state. Multiple Hosts, etc.

Proposed changes

If you deploy a master ingress with no minion. It logs the entire Ingress name.

Ignoring Ingress cafe-ingress-tea-minion(Minion): 
Could not find a Master for Minion: 'default/cafe-ingress-tea-minion'
