[TABJS-13] Add txn hash in shell responses

[dtbuchholz]

Summary

When working with the shell command, it'd be nice to get a transaction hash in the response after a mutating query is made. For example, the following query is invalid for a table t_31337_2 with schema i int, v text:

insert into t_31337_2 values (1, 0xf95980ee414ff1b68d66421500d4779b6d453c5e);

However, the information logged is simply:

{"updatedTable":"t_31337_2"}

When I go to query the table, there is no data (as expected), but I have no clue why since I do not have the txn hash.

Details

There are a couple of options. You could choose to add the txn hash to the mutation response where the information logged could be:

{"updatedTable":"t_31337_2", "txn_hash": "0x1234..."}

Alternatively, you could choose to not log a misleading updatedTable (since it wasn't updated), catch the error, and then log it on the spot (and include the txn hash, too).
