Automatically select 1st slide for presenter

```
What steps will reproduce the problem?
1. Login as presenter
2. Upload slides

You expect to see the first slide, but the presentation shows the
thumbnails but no slide.

Currently, presenter needs to click the first slide.  The client should
show the 1st slide automatically.
