Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

While creating a minimal test case for #3303, I managed to create images that I was unable to remove, even using -f.

Steps to reproduce the issue:

1. Create the Dockerfile

   $ echo 'FROM scratch
   LABEL org.opencontainers.image.authors="<somefolks@example.org>"
   LABEL org.opencontainers.image.created=2019-06-11T19:03:37Z
   LABEL org.opencontainers.image.description="This is a test image"
   LABEL org.opencontainers.image.title=test
   LABEL org.opencontainers.image.vendor="Example.org"
   LABEL org.opencontainers.image.version=1' > Dockerfile
   

2. Build the image

   $ podman build .
   STEP 1: FROM scratch
   STEP 2: LABEL org.opencontainers.image.authors="<somefolks@example.org>"
   --> 4ebea5977ec0993c77b4a614225076640a00883b72bee1b9e16aa1f7bba35d45
   STEP 3: LABEL org.opencontainers.image.created=2019-06-11T19:03:37Z
   --> 93f759f779d94830bf362b9c884346bf5a34f835fb50e3e717e7adbbf7f1afd7
   STEP 4: LABEL org.opencontainers.image.description="This is a test image"
   --> 2574ed1a96155670e8a139a39011dd5fc07f931d4cd235aebed0f50b1fa7314c
   STEP 5: LABEL org.opencontainers.image.title=test
   --> 619b496ce10a0f32051114a0feaabc33c59d1fafd66b517fca122ed8a214d486
   STEP 6: LABEL org.opencontainers.image.vendor="Example.org"
   --> 7aed0f33d0ad9f9b8c018fabb3e9470e0cc5101e5389a62186e40e43bf6500a4
   STEP 7: LABEL org.opencontainers.image.version=1
   STEP 8: COMMIT
   --> f881d3aec74db46b890745b89169333c5628bd588db5c5d698ab9ddc076a172e
   

3. Try to delete any of the built images

   $ podman image ls
