Log Level for CUBEJS_LOG_LEVEL is not working.

**Describe the bug**
I am trying to get only errors by setting CUBEJS_LOG_LEVEL=error but thats not working.

**To Reproduce**
Steps to reproduce the behavior:
1. Setup Cube JS basic app from CubeJS CLI
2. Set CUBEJS_DEV_MODE=false
3. Set CUBEJS_LOG_LEVEL=trace
4. Add this in cube.js file
`module.exports = {
logger: (msg) => {
console.log(msg);
}`
5. Try to run /cubejs-api/v1/load api end point. See the output in console

`REST API Request

6. Now, try the same with CUBEJS_LOG_LEVEL=error. You will get the same output.

**Expected behavior**
I expected only errors when CUBEJS_LOG_LEVEL=error.
