Error in one query makes subsequent queries fail

[Anand Chitipothu]

The following test fails.

    def testWrongQuery(self):
        # It should be possible to run a correct query after getting an error from a wrong query.
        try:
            web.select('wrong_table')
        except:
            pass
        web.select('person')

Here is exception trace:
