bill status errors with 'as amended', ping-pong votes, and conference reports

* On the first vote in the second chamber, we were not handling 'as amended' for joint/concurrent resolutions, so we were prematurely marking these as PASSED when they should get a PASS_BACK status.
* On ping-pong votes, we were not handling 'as amended' at all, so we were prematurely markinig these as PASSED when they should be PASSED_BACK.
* Ping-votes and votes on conference reports were also not handling joint/concurrent resolutions, and on a successful ping-pong/conference report vote these were incorrectly given the status PASSED:BILL, instead of PASSED:CONSTAMD/PASSED:CONCURRENTRES.
