Fixes compatibility for tests running against Juliav1.8

[BaileyBox]

When running Impute.jl tests against Julia1.8, we run into a problem when calling the nrmsd() function here (from Distances.jl, function found here).

There error we get is as follows:

Since there were some changes/refactoring to the extrema() function, it created a MethodError, where it couldn't match the adjoint() method with what we passed in (adjoint(data) from within the failing test).

Flipping the two around fixes the tests, but not the root of the problem. I'm not sure if this is the correct solution, or if I have to report this as an issue with JuliaLang itself. I know a bunch of other stuff changed around mapping, so maybe this isn't a problem here, but a new limitation with the language itself.

Happy to hear some feedback about this :)

@rofinn is it correct to swap these 2 around to fix this? Or should I try to find another solution (Reporting bug to JuliaLang)?

A bit annoying that it needs to change, but this seems fine to just modify the tests. It doesn't impact the actually functionality, so make sure to remove the version bump.

I'm unsure why the x64 julia check failed, when the exact same test passed previously.
