Provide full Python stack trace details when in a JS context

closes #270

We still have cases where the stack is missing:

due to not having entered the python function at all: we can't get into its code because we can't properly give it args to run with

So this one can generate a stack for us:
items = [4,2,6,7]
def myFunc(e,f):
return len(e) - len(f)
pm.eval("(arr, compareFun) => {arr.sort(compareFun)}")(items, myFunc)
-> object of type 'float' has no len() (edited)

but these two can't:
items = ['Four', 'Three', 'One']
def myFunc(e):
return len(e)
pm.eval("(arr, compareFun) => {arr.sort(compareFun)}")(items, myFunc)
-> takes 1 positional argument but 2 were given

items = ['Four', 'Three', 'One']
pm.eval("(arr, compareFun) => {arr.sort(compareFun)}")(items, len)
-> len() takes exactly one argument (2 given)

but then the error message is rather revealing and gives us a direction to work into
