Logging does not seem to work in browser

### How are you using the `@globus/sdk`?

Client-side JavaScript (e.g. Browser)

### Current and expected behavior

I initialise the logger as follows, in a React single page app :

```
import { authorization, logger } from "@globus/sdk";

logger.setLogger(console)
logger.setLogLevel('debug')

```

It has no effect, i.e. no log message appear in the browser console, despite multiple calls to the API.

Lookin at the code (authenticationManager, etc, I see plenty of logging messages, ex: log('debug', 'AuthorizationManager.handleCodeRedirect') that I should be seeing in the console.

### Environment
