Fixes #1316
Currently,
verbose()
adds trace info to the error object only if youthrow
the error by catching it inside a try/catch :https://github.com/mapbox/node-sqlite3/blob/afa22076ba13ef3bc6afac892d9ed46a7ec36fc2/lib/trace.js#L18-L28
This doesn't work with promises as discussed in the linked issue because throwing in an async callback doesn't get caught by the promise or a wrapping try/catch.
this PR solves this issue by simply adding the trace info outside try/catch by checking the error object which is always the first argument.
