There were an arror in commit ID parsing from the output of:
  $ ostree admin status
  * apertis 334f57354221f0800b008d043c5c50683e83e8b6afa5880e95449a980132fa83.0
      origin refspec: origin:apertis/v2021pre/armhf-uboot/minimal
    apertis bab35cb1fe04e2fc11c3b462ebac0e38640173ebcff55ca326f838296a0121f5.0 (rollback)
      origin refspec: origin:apertis/v2020/armhf-uboot/minimal

Some test contains incorrect boot ID detection, including the suffix
`.0` which is an error. Hence fixing the issue in the initial script and
all copy-paste copies.
