Writer tests broken by Blissterm UI refactor
This MR broke the writer tests:
The CI of the MR said so
https://gitlab.esrf.fr/bliss/bliss/-/jobs/952613
The tests are broken because of this commit:
When the ESRF data policy is disabled (beamline name in SCAN_SAVING) the test did not expect a beamline name in the HDF5 file.
Adding the beamline name to the Beacon configuration does cause the beamline name to be on the HDF5 file, data policy enabled or not.
