Fix to `check_cuts_considered`

Created by: scarlehoff

At some point check_cuts_considered started being used for the fits, resulting in the following error when running the NLO runcards for instance.

Cuts must be computed for this action, but they are set to fromsimilarpredictions

The check was only accepting fromfit and internal, now it accepts anything that isn't "nocuts".

Maybe it wasn't a bug but a feature though.
