ORTCDemo: focus state for "connect" button is not obvious enough

Changes from transparent background to white, which is very similar. 

It looks like the styles are busted as no top margin (owl removal probably) and the hover state is blue.

@dstorey @sarvaje This demo is external, namely, it's from https://ortcdemo.azurewebsites.net.

We have access to that server. Don't know where the code is but we can modify the templates directly if needed. Erik should know more and @sarvaje should have access to it via the azure portal.

Yep, I have access to the server so I can change the css directly. @dstorey is it good just to change the current focus style for the hover style (the blue color)

@sarvaje it should probably have something similar to the edgeCore focus styles, as if use same as hover it would be obvious that they're different. Maybe @melanierichards can chime in.
