Google Batch: `outputDir` directive workflow cannot be anything but the bucket

[VasLem]

Bug report

Anything that comes after the bucket in the outputDir directive is ignored.
Example:

outputDir = "gs://MY_BUCKET/dir1/dir2"

process test {
input:
val(counter)
output:
tuple val("test_loc/${counter}"), val(counter), path("output.txt")
script:
"""
touch output.txt
"""
}

workflow {
main:
counter_channel = channel.fromList((1..10).toList())
to_publish = test(counter_channel)
publish:
to_publish = to_publish
}

output {
    to_publish {
        mode 'copy'
        path { odir, counter, _fname->
         odir }
    }
}

Output is saved in:

gsutil ls  "gs://MY_BUCKET/test_loc"
1 2 3 4 5 6 8 9 10
