patch 8.0.0698: crash on exit when using Python function in timer.
Problem: When a timer uses ":pyeval" or another Python command and it
happens to be triggered while exiting a Crash may happen.
(Ricky Zhou)
Solution: Avoid running a Python command after python_end() was called.
Do not trigger timers while exiting. (closes #1824)
