Auto merge of #1183 - bitcartel:zc.v0.11.2.latest_txid_tests, r=bitcartel 

Add gtest for non-malleable txids.

1. Test txid of normal transaction is double sha256 with sigscript input data removed
2. Test txid of coinbase transaction is double sha256 over whole tx

You can run a single test with:
./zcash-gtest --gtest_filter="txid_tests*"
