remake no longer works for ODE-jump models

[isaacsas]

The following worked on 9.69 but does not work on 9.72:

using ModelingToolkit, JumpProcesses
t = ModelingToolkit.t_nounits
D = ModelingToolkit.D_nounits
@variables X(t)
@parameters a b
eq = D(X) ~ a
rate = b*X
affect = [X ~ X - 1]
crj = ConstantRateJump(rate, affect)
@named jsys = JumpSystem([crj, eq], t, [X], [a,b])
jsys = complete(jsys)
oprob = ODEProblem(jsys, [:X => 1.0], (0.0, 10.0), [:a => 1.0, :b => .5])
jprob = JumpProblem(jsys, oprob)  
jprob2 = remake(jprob; u0 = [:X => 10.0]) 

gives

ERROR: UndefVarError: `X(t)` not defined in local scope
Suggestion: check for an assignment to a local variable that shadows a global of the same name.

Some type information was truncated. Use `show(err)` to see complete types.

The same error about X(t) is given if one tries to update a parameter

jprob2 = remake(jprob; p = [:a => 10.0])

Awesome, thanks for the quick fix! We'll add this back into the Catalyst tests too once released.
