Cache should detect locally built image with different name when push fails

[nkubala]

a common build failure scenario is forgetting to apply a default repo, meaning that images build fine but skaffold will fail because of a failed push. once a default repo is applied, the subsequent build and push will succeed, but rebuilds shouldn't be necessary if the previous build succeeded. however, skaffold's cache check is naive in checking for a direct image name match, and will fail and rebuild, which can be annoying with long image builds.

Expected behavior

after successful build but failed push, subsequent build/push should detect image built locally if name changes (but tag stays the same)

Actual behavior

cache check fails because image name has changed

Information

• Skaffold version: v1.14.0
• Operating system: all

Steps to reproduce the behavior

1. https://github.com/GoogleCloudPlatform/bank-of-anthos
2. skaffold build # build with succeed, but push will fail
3. skaffold build -d <repo_with_push_access>
