tests: fix test_stacktrace_big_recursion failure due to argv

[booxter]

Sometimes I see the test failing because the event contains extras
with sys.argv key in addition to exception. There's probably some
state leaking between tests, but regardless this patch should make the
test case slightly more robust.

Thank you @booxter!

We definitely have some stuff leaking between the tests, we need to allocate proper time to figure out how to fix that. Your fix is definitely a good improvement though!

Feel free to also bump the timeout in this PR.
