Screenshot of wizard with "Try Sample Repository" link which fails to populate extra fields.

Description of problem:
There seems to be a regression in the formerly known "Try It" feature what now seems to be called "Try Sample Repository".

See this issue for details:
https://github.com/redhat-developer/s2i-dotnetcore-ex/issues/33

The imagestream in question has "sampleContextDir" and "sampleRef" annotations. Those were properly populated to the correct fields in older OpenShift versions.

In latest OpenShift Online those are not taken into account and, thus, deployment fails for the users. If they get correctly set via advanced settings things start to work.

These versions worked fine with the image stream[1]:

OpenShift Master:  v3.6.0+c4dd4cf
Kubernetes Master: v1.6.1+5115d708d7

These versions seem to be broken:

OpenShift Master:  v3.7.9 (online version 3.6.0.73.0)
Kubernetes Master: v1.7.6+a08f5eeb62
