Add test file for paste module.

test/extra/paste_test.py

+# expected: fail

+# The paste test suite uses pytest, so this test file incentally also tests pytest.
+# Pytest relies quite heavily on a number of code introspection features, which
+# we currently don't have. This includes:
+# 1) The ast module
+# 2) traceback.tb_frame, traceback.tb_next
