Fix remake for SCCNonlinearProblem

[SebastianM-C]

It looks like the explicitfuns! argument is directly forwarded to the constructor resulting in broken problems after a remake due to explicitfuns! being missing.

We have a test somewhere for newprob = remake(prob::SCCNonlinearProblem). Could you check that @test newprob.explicitfuns! !== missing?

We have a test somewhere for newprob = remake(prob::SCCNonlinearProblem).

I haven't found any test for SCCNonlinearProblem in in the remake tests 😅
I added some minimal tests for remake(prob::SCCNonlinearProblem), let me know what you think.

Edit: Ah, they are in downstream testing. I added the test there.
