fix: Sync ScopeListeners

[HazAT]

We have a race condition in the electron SDK where we set the user on the scope but since we call the notifies in setTimeout the user is not properly propagated to the main process.

So if you have this for example:

configureScope(scope => {
    scope.setUser({ id: 'abc' }); // This invokes notify scope listeners
  });
}

captureException(new Error('test'));

On electron, we sync the scope across different processes via IPC calls.

The previous code resulted in:

IPC -> captureException
IPC -> Scope update

after the change, because we are removing the setTimeout

its:

IPC -> Scope update
IPC -> captureException
