Fix unknown process type warnings

[Zaharid]

Running comparefits we get a bunch of

[WARNING]: Unknown process type for dataset CHORUSNUPb_dw_ite

These should not be there.

It's weird because that dataset does have a process set in the plotting file.

dataset_label: "CHORUS $\\sigma_{CC}^{\\nu}$"
x: k2
y_label: '$10^{i}\sigma_{CC}^{\nu}(x,Q^2)$' 
result_transform: qbindis
kinematics_override: dis_sqrt_scale
data_reference: Onengut:2005kv

#x_scale: log
y_scale: symlog
line_by:

normalize:
    y_scale: linear
    line_by: []
    figure_by:

@Zaharid when I run vp-comparefits I get unknown process type for the following, but not the dataset you mentioned. Are your PLOTTING files definitely up to date?

@RosalynLP not sure, but that was an example. In any case, we should not have any warnings and instead get that information from the plotting file and only if neccesary. Note this is already done as part of the grouping functionality. But this is not using that
