vim-patch:8.2.3448: :endtry after function call that throws not found

Problem:    :endtry after function call that throws not found.
Solution:   Do check for following :endtry if an exception is being thrown.
            (closes vim/vim#8889)

Nvim obsoleted did_throw; check current_exception is not NULL instead.
