Biosimulators copasi gives incorrect results that normal copasi doesn't

[luciansmith]

The attached OMEX files all produce different results on copasi-on-biosimulations than they do for copasi-on-my-desktop (or, for that matter, from tellurium-on-biosimulations).

BIOMD0000000005.omex.zip BIOMD0000000006.omex.zip BIOMD0000000007.omex.zip

The phenotype is the same for all: a value that should change in time instead is fixed and doesn't change. For Biomodels 5, the variable in question is YT, aka 'total_cyclin'. You can see the difference in

@fbergmann : Just in case you have an idea of how someone might accidentally tell Copasi to leave something fixed.

[fbergmann]

I think the biosimulator_copasi does use the utils to apply changes, rather than let COPASI do it. So the error would have to be fixed there, as it would apply to more biosimulators.

This is now fixed!
