[test] sending invalid msgs to node with bloomfilters=0 causes discon…

…nect

-A node with bloomfilters disabled should disconnect peers that send
msg_mempool, msg_filterload, or msg_filteradd.
-Renamed the test because it now has a wider scope and msg_mempool's
actual functionality makes more sense for p2p_filter.py.
