ff22751417c6fbbd22f4eefd0e23431a83335c13 test: rm ascii art in rpc_fundrawtransaction (Jon Atack)
94fcc08541cf58bee864ab7c28a6c77e42472f17 test: add rpc_fundrawtransaction logging (Jon Atack)

Pull request description:

  `test/functional/rpc_fundrawtransaction.py` is fairly slow to run and has no logging, so it can appear to be stalled.

  This commit adds info logging at each test to provide feedback on the test run.
