Stack trace is included in responses

[mcoughlin-bw]

Describe the bug
I'm receiving stacktrace information in "load" responses despite having CUBEJS_DEV_MODE set to false.

To Reproduce
Steps to reproduce the behavior:

1. Setup your queryRewrite function to throw an error
2. Send a request to "load" that hits the queryRewrite function
3. Check the API response. It will include "stack" information

Expected behavior
Stack information should not be present when CUBEJS_DEV_MODE is set to false.

Version:
0.32.14
