WITH DOCKER with multiple --load from same target doesn't load images properly

[ohadravid]

Hi!

I'm facing an issue when using WITH DOCKER with multiple images which are loaded from a target with the same name.

Running earthly -V -P +test (using earthly version v0.4.3) for the following Earthfile (in an empty folder):

docker:
    FROM ubuntu


test:
    FROM earthly/dind:alpine
    WITH DOCKER \
            --load a:latest=+docker \
            --load b:latest=+docker
        RUN docker images
    END

results in:

...
+test | --> WITH DOCKER (install deps)
+test | /usr/local/bin/dockerd
+test | Completed in 302.1184ms
+test | --> WITH DOCKER RUN docker images
+test | Loading images...
+test | Loaded image: a:latest
+test | Loaded image: a:latest
+test | ...done
+test | REPOSITORY   TAG       IMAGE ID       CREATED          SIZE
+test | a            latest    abe76754ebd5   51 minutes ago   72.9MB
+test | Completed in 4.4538029s
...

where the expected output should show both a and b images.

My workaround for now is this:

docker:
    FROM ubuntu

a:
    FROM +docker

b:
    FROM +docker

test:
    FROM earthly/dind:alpine
    WITH DOCKER \
            --load a:latest=+a \
            --load b:latest=+b 
        RUN docker images
    END

which seems to work as expected.

Thanks for this great tool!
