Error not being thrown when there is a bug in a `Prc`

[hdavid16]

See: #49 (comment)

There is an error in the original function used to create a Prc (with the @process macro). However, the error is never thrown. @pbayer any thoughts?

Here is a MWE:

using DiscreteEvents
function time(c)
    @delay c 1
    println("Time is $(c.time)")
    error("random error")
end
c = Clock()
process!(c, Prc(time))
run!(c, 10)

The simulation ends at the error with no error thrown. Commenting the error will run the time function every 1 unit until 10 units are simulated.

I have pinpointed where the issue occurs:

DiscreteEvents.jl/src/events.jl

Line 29 in 4a9fab4

_evaluate(ev.ex)

When the error is not present, a new event is scheduled for t = 2 when _evaluate is called. When the error is present, the error is not thrown and the new event is not scheduled for t = 2.
This is as far as I can go with the debugger. Any thoughts @pbayer ?
