According to [the docs][1], `exitOnUncaughtException` should:
> Exit the process after handling an uncaught exception. Requires
> `captureUncaught` to also be set.
So with this config:
```js
var rollbar = new Rollbar({
captureUncaught: true,
exitOnUncaughtException: true,
// ...
});
```
...an uncaught exception should exit the process.
This works correctly, but *only* if `rollbar.configure()` is *never*
called again, because:
1. `exitOnUncaughtException` [was deleted][2] from our options
2. Calling `configure()` calls [`setupUnhandledCapture()`][3]...
3. ...which calls [`handleUncaughtExceptions()`][4]...
4. ...which now [tries to access][5] `options.exitOnUncaughtException`
5. But this option was deleted in Step 1, so when we [replace][6] our
`uncaughtException` handler, we now have `exitOnUncaught = false`
This change:
- no longer deletes `exitOnUncaughtException` from options (it's
unclear why this is the only option that is deleted)
- directly accesses `options.exitOnUncaughtException` in the
handler, just like `options.captureUncaught` is accessed directly
