build: image is not used if image: is also set

[bam80]

If both build: and image: are present, the image builds but is not used, and it's impossible to make use of it even with --build option:

  web:
    image: caddy:alpine
    build: .

Run the service:

$ podman-compose --verbose run --rm --service-ports --build web
...
INFO:podman_compose:podman build -f Containerfile -t caddy:alpine <compose dir>
...
# <compose dir>_web:latest is built..
Successfully tagged localhost/caddy:alpine
Successfully tagged localhost/<compose dir>_web:latest
...
# ..but is not used then - downloaded caddy:alpine is run instead
INFO:podman_compose:podman run ... caddy:alpine

If we remove image:, the image built is used then properly:

  web:
    build: .

$ podman-compose --verbose run --rm --service-ports --build web
...
# <compose dir>_web image is run properly
INFO:podman_compose:podman run ... <compose dir>_web

This behavior doesn't correspond to docker-compose, where build: has a preference.
