Russell Yanofsky b4bc32a451 [wallet] Get rid of CWalletTx default constructor 
No change in behavior in the normal case. But buggy mapWallet lookups with
invalid txids will now throw exceptions instead of inserting dummy entries into
the map, and potentially causing segfaults and other failures.

This also makes it a compiler error to use the mapWallet[hash] syntax which
could create dummy entries.
