Description of problem:
If the default app name is changed, pod is not created when deployed from ImageStreamTag on web console

Version-Release number of selected component (if applicable):
v3.3.0.30

How reproducible:
Always

Steps to Reproduce:
1. Login to Openshift web console and create a new project
2. Add to project -> Deploy Image -> Image Stream Tag
3. Choose one istag, e.g. openshift/mongodb:latest, then change the default app name "mongodb", e.g. to "mongodbxxia", then click "Create"
4. Check pod 

Actual results:
3. Return creation success
4. No pod. If check `oc deploy mongodbxxia`, it shows "mongodbxxia deployment #1 waiting on image or update", even after waiting some time.

Check the dc, found:
$ oc get dc mongodbxxia -o yaml
  triggers:
  - type: ConfigChange
  - imageChangeParams:
      automatic: true
      containerNames:
      - mongodbxxia
      from:
        kind: ImageStreamTag
        name: mongodbxxia:latest   <-- the cause
        namespace: openshift
    type: ImageChange

However:
A. If don't change the default app name, then pod will be created
B. Even if default app name is changed, corresponding CLI approach can quickly see created pod:
$ oc new-app mongodb:latest --name mongodb2nd
$ oc deploy mongodb2nd
mongodb2nd deployment #1 deployed about a minute ago - 1 pod

C. Even if default app name is changed, another choice "Deploy Image -> Image Name" can quickly see created pod as well.

Expected results:
4. Should see created pod.
