ErrMultipleImages does not work

[mtrmac]

From #8176 (comment) , not fixed in #8609:

• If findImageInRepoTags fails with errors.Wrapf(define.ErrMultipleImages, searchName)
• The caller in

  podman/libpod/image/image.go

  Lines 496 to 500 in f01630a

  	if err == nil {
  	return inputName, repoImage, nil
  	}
  	return "", nil, errors.Wrapf(ErrNoSuchImage, err.Error())

  just throws away that value and returns ErrNoSuchImage…
• … causing the error value check in

  podman/pkg/domain/infra/abi/images.go

  Lines 43 to 44 in f01630a

  	if errors.Cause(err) == define.ErrMultipleImages {
  	return &entities.BoolReport{Value: true}, nil

  to not trigger, and Exists to return false.
