Add missing 'check' argument to several divexact methods

[fingolfin]

We need this in order to write generic code

[fingolfin]

Turns out there were also a few divexact methods which had a check argument but it was positional, not a keyword argument... The second commit now fixes these. But I guess this makes this technically speaking a breaking change, in case anyone was using this third argument sigh.

I will add compatibility shims to src/Deprecations.jl to avoid the breakage
