Fix -netinfo backward compat with getpeerinfo pre-v26

Browse Source 
CLI -netinfo will currently break when calling it on a node that is running
pre-v26 bitcoind, as `getpeerinfo` doesn't yet return a transport_protocol_type
field.

Fix this by adding an `IsNull()` check as already done for other fields, and also:

- avoid checking for the full string "detecting", and instead do the cheaper
  check for the most frequent case of the string starting with "v"

- drop displaying the "v" prefix in all the rows, as it doesn't add useful
  information, and instead use "v" for the column header

- display nothing during peer setup, like for the -netinfo mping and ping columns
