Latexify display does not work for `SDESystem`s

[TorkelE]

Not sure if this should be here or in Latexify.

Example:

using ModelingToolkit

# Define some variables
@parameters p d 
@variables t X(t)
D = Differential(t)
eqs = [D(X) ~ p - d*X]
noise_eqs = [sqrt(p), sqrt(p - d*X)]

@named ssys = SDESystem(eqs, noise_eqs, t, [X], [p, d])

Basically, the noise equations just gets dropped.

I think the latexify function just needs to add the other function call to it.

The noise equations are added in the current docs versions.
