Scan crashes if chip config is used from crashed analysis

If the chip config is used from a previous a scan with a crashed analysis step the scan crashes with the following error:

Loading chip configuration for chip 0x0001 from /home/silab/git/bdaq53/bdaq53/scans/output_data/module_0/chip_0/20201030_141821_fast_threshold_scan_interpreted.h5

I think this should not be like that.
