Handle the case where start is greater than end in list.index()

[faze-geek]

A rather unlikely edge case -

def f():
    lst :list[i32] = [1, 2, 3]
    print(lst.index(2,2,1))

f()

On master :

(lp) C:\Users\kunni\lpython>python try.py
Traceback (most recent call last):
  File "C:\Users\kunni\lpython\try.py", line 5, in <module>
    f()
  File "C:\Users\kunni\lpython\try.py", line 3, in f
    print(lst.index(2,2,1))
ValueError: 2 is not in list

(lp) C:\Users\kunni\lpython>src\bin\lpython try.py
2

On branch :

(lp) C:\Users\kunni\lpython>src\bin\lpython try.py
ValueError: The list does not contain the element: 2

I think that looks good, thanks!
