Unable to enforce custom image tags

[Mulan-94]

I'm trying to use a specific cab image tag different from the default specified in the cab parameters. However it seems the default version is still use. This is what I was trying:

recipe = stimela.Recipe(
                     "Testing spimple imconv",
                     msdir=MSDIR, JOB_TYPE="singularity",
                     singularity_image_dir="stimelarity",
                    cabspecs={"tag": "1.7.2b", "force": True}

Not sure if this is related, but this issue seems to cause an issue in caracal for @francescaLoi, whereby one is unable to specify a specific image tag. Here are some sections of the logfile showing this behaviour:
