Android reports of failure to authorize w/ Opera

Issue

I've received several reports this week from users who are unable to authorize using this library on Android, and the common thread seems to be that they are on the latest version of Opera. It seems like the underlying OpenId project that this wraps has some reports about this issue as well.

Curious if other people have seen anything like this. So far I've been unable to reproduce it on a simulator, even when disabling Chrome on the device completely.

Same problem, set Opera as a default browser and application crashes when call authorize.

RN: 0.59.9

Hi 👋 - looks like AppAuth-Android doesn't currently support Opera. There is an open PR that should solve this.

While we're waiting for the fix, I'm updating the error messaging to return browser_not_found when a suitable browser could not be found. Not ideal, but at least this will avoid a native crash and allow displaying a useful error message.
