__knexQueryUid not generated for ROLLBACKs

[pdemarino]

Environment

Knex version: 0.20.7
Database + version: MySQL 5.6 (RDS)
OS: Lambda

Bug / Missing documentation?

Issue

Rollbacks generated by Knex should lead to a unique query ID being generated and reported through the event mechanism (Knex.on("query-response", (resp,obj)=> { ... }).

Instead, I am seeing events like these:

"obj": {
        "__knexUid": "__knexUid1",
        "__knexTxId": "trx2",
        "sql": "ROLLBACK"
    },

I also noticed this missing from a number of table definition calls.

"obj": {
        "__knexUid": "__knexUid1",
        "__knexTxId": "trx2",
        "sql": "alter table `wss_tokens` add index `wss_tokens_user_sub_index`(`user_sub`)",
        "bindings": []
    },

I have noticed this bug also occurs for "CREATE TABLE" queries.
