MOF `read_from_file` fails when using MOI.Parameter and non-linear constraints

[odow]

Do

model_test = read_from_file("test.mof.json"; use_nlp_block = false)

I might need to think about how we can do this automatically: [FileFormats.MOF] add a flag to the file when use_nlp_block=false · Issue #2687 · jump-dev/MathOptInterface.jl · GitHub
