Committed by Buristan

Commit Message

Fix VM event error handling for finalizers.

Reported by Sergey Kaplun.

(cherry picked from commit fbb36bb6b)

After the previous commit, the VM handler for the 'errfin' VM event
works incorrectly. The error object is taken not from the stack on which
the VM handler is invoked. Hence, it breaks the non-VM stack and returns
an incorrect error message.

This patch fixes the issue by copying the object from the corresponding
Lua stack.

Sergey Kaplun:
* added the description and the test for the problem
