`pull_policy` of `build` is ignored

**Describe the bug**
I have a `compose.yaml` file where I want the service's image to be rebuilt every time it is started, using the below:

- `compose.yaml`
```yaml
name: myservice

services:
myservice:
build:
context: .
dockerfile: Dockerfile
image: localhost/myservice
pull_policy: build
container_name: myservice
```
- `Dockerfile`
```Dockerfile
FROM quay.io/podman/hello

COPY example.txt example.txt
```
- `example.txt`
```txt
example
```

However, the `build` value for `pull_policy` seems to be ignored, resulting in the image not being rebuilt. Normally the image should be rebuilt on every start (even when there are no changes to the `Dockerfile`), but this is not happening (even if I make changes).

If the image does not exist already, then it will be built, albeit after throwing an error:

> Error: inspecting object: unable to inspect "localhost/myservice": failed to find image localhost/myservice: localhost/myservice: image not known

**To Reproduce**
Steps to reproduce the behavior (all in the same directory):
1. Create the above files
2. Run `podman-compose up`
3. Run `podman-compose down`
4. Run `podman-compose up`

**Expected behavior**
The `localhost/myservice` image to be built on both executions of `podman-compose up`.

**Actual behavior**
The `localhost/myservice` image was only built on the first execution of `podman-compose up`.

**Output**
