[3.1 -> main] Fix log trimming of hex_data JSON output.

[heifner]

Merge issue of #190 missed trimming the "hex_data" attribute in logged transaction trace data.

Added transaction_trace_success and transaction_trace_failure trace loggers to eosio-launcher to provide additional logging during tests.

Example:
