test: Fix functional tests to work with new blockfilterindex defaults

Three tests needed updates to work with the new defaults where
-blockfilterindex=basic and -peerblockfilters=true:

- p2p_blockfilters.py: Explicitly disable peerblockfilters for node 1
  which doesn't serve compact filters
- rpc_getblockfilter.py: Explicitly disable both options for nodes that
  should not have block filter index
- rpc_misc.py: Explicitly disable both options when testing the absence
  of indices
