Pull request description:

  Speed up rpc_fundrawtransaction.py

  Most of the time in rpc_fundrawtransaction.py is spent waiting for
  unconfirmed transactions to propagate. Net processing adds a poisson
  random delay to the time it will INV transactions with a mean interval
  of 5 seconds. Calls like the following:

  ```
  self.nodes[2].sendrawtransaction(signedTx['hex'])
  self.sync_all()
  self.nodes[1].generate(1)
  ````

  will therefore introduce a delay waiting for the mempools to sync.
  Instead just generate the block on the node that sent the transaction:

  ```
  self.nodes[2].sendrawtransaction(signedTx['hex'])
  self.nodes[2].generate(1)
  ```

  rpc_fundrawtransaction.py is not intended to be a test for transaction
  relay, so it's ok to do this.
