Operation times a sparse array errors

[caryan]

Using ModelingToolkit v3.4.0 and julia 1.4.0 I'm trying to multiply an operation by a sparse array and not having any luck:

julia> using ModelingToolkit

julia> using SparseArrays: sparse

julia> @parameters ω
(ω,)

julia> X = Float64[[0 1]; [1 0]]
2×2 Array{Float64,2}:
 0.0  1.0
 1.0  0.0

julia> ω.*sparse(X)
ERROR: TypeError: non-boolean (Operation) used in boolean context

Thanks for the issue. Yes, this seems to be a missing method that can cause some trouble. We'll have to write a workaround.
