Fix ft0reco crash

Recent disabling of FT0 calibrations in the reco workflow
internally disables the CCDB fetcher. In result, the option --condition-not-before
vanishes and the workflow crashes when the option is given on the command line.

This is a generic problem with "dynamic" options.

For now fixing, by taking away this option for FT0 reconstruction.
