Incorrect container name in deployment trigger annotation

Description of problem:

Wrong container name is getting added in the deployment trigger annotation when deployment is created using container image add flow.

Steps to Reproduce

1. Create an imagestream in your project
2. Go to container image flow and select the previously created imagestream
3. Keep the deployment name different from the imagestream name
4. Click on create

Trigger annotation incorrectly uses imagestream name as container name
