Namespace production rules give wrong results for implicit keys

[Zaharid]

The following validphys runcard

theory:
    from_: fit

theoryid:
    from_: theory

use_cuts: "fromfit"

pdf:
    from_: fit

experiments:
    from_: fit

dataspecs:
  - fit: NNPDF31_nlo_as_0118_1000

  - fit: NNPDF31_nnlo_as_0118_1000

actions_:
    - matched_datasets_from_dataspecs::dataspecs plot_fancy_dataspecs

gives the wrong results in that the datasets incorrectly resolve to the first (NLO) value. It works fine if

experiments:
    from_: fit

is inside each dataspec. This has to do with the fact that even though we specify write=False in the validphys production rules, the parameter is not propagated to resolve_signature_params. This change:

appears to fix the problem, but then some other test fails. Have to check if correctly propagating the argument works. Or rewrite the whole thing in a way that is not crazy.
