Fix image component handling, honoring Installation spec

[petrutlucian94]

components.GetReference currently ignores the image prefix and path specified in the "Installation" spec.

It makes a copy of the image component, appends the configured image path and prefix but then it uses the original component image when looping over the image set.

The fix is trivial, we just have to use the modified image string.

Looks like there is another blocker that prevents us from using custom built images. We could pass in the install spec (or just the image path/prefix) and apply them just like GetReference does.
