[wallet] Construct CWalletTx objects in CommitTransaction

Browse Source 
Construct CWalletTx objects in CWallet::CommitTransaction, instead of having
callers do it. This ensures CWalletTx objects are constructed in a uniform way
and all fields are set.

This also makes it possible to avoid confusing and wasteful CWalletTx copies in
https://github.com/bitcoin/bitcoin/pull/9381

There is no change in behavior.
