second arquillian test now fails on minishift

[jstrachan]

to reproduce:

• create a microservice app on minishift + fabric8
• update the source code to trigger a second build
• the 2nd system test now fails

It seems to update the DC and there's a new RC but no pods run. Bizarrely you can manually scale the new RC by hand then it works (if you're quick enough before the failure of the ARQ system test)

the reason could well be a timeout on minishift - see https://github.com/fabric8io/fabric8/issues/6575#issuecomment-262022833
