state.event runner does not display events if using eauth.

Description of Issue/Question

Set up eauth and use the state.event runner to try showing the events coming through the master.

The command will run and display nothing. Other runners work fine.

Setup

I setup master stats and the status beacon so I would have an almost constant stream of events.
and then ran salt-run -a pam state.event pretty=true and waiting. nothing ever showed up. Was asked to log in and then no output.

When run without -a pam events start pouring in without much wait.

Steps to Reproduce Issue

• Setup eauth
• make sure events are being generated.
• salt-run -a pam state.event pretty=true and wait for an event

Again also happens in 2018.3 so also not a regression. or a very old one.

Start by reproducing the issue with the state.event runner and salt-run -a pam state.event pretty=true, using the eauth and status-beacon setup described. Trace the eauth execution path and compare it with unauthenticated state.event; done means events are displayed when authentication is enabled.
