[Media Router WebUI] Handle route details in incognito.

While we currently don't support split mode for the extension, we cannot do any toplevel navigations with the component extension with extensionview. Thus, anyone trying to view the route details in incognito mode will see a "This site can't be reached" error message if there was custom controls available for the route.

This change only shows the default route details description when the browser is "off the record", aka in incognito mode.

Jennifer, do we need to merge this back to M51?

[Automated comment] Less than 2 weeks to go before stable on M51, manual review required.

Before we approve merge to M51, Could you please confirm whether this bug is baked/verified in Canary and safe to merge?

gorvind@: This has been in Canary for a few weeks now and should be safe to merge as it only affects Media Router. 

Merge approved for M51 (branch 2704)

Please merge your change to M51 branch 2704 asap as we're getting closer to M51 stable promotion.

I still see the "This site can't be reached" issue with 
MR: 5216.530.0.0					
Chrome: 52.0.2743.10					
On Mac

However, after ~ 1 minute, the issue goes away and shows the correct "Casting" label.

this occurs every time.

Another detail about it going away. It shows the correct thing after ~ 1 min of the dialog being open, then when re-opened the bug re-appears.

dbbrooks@: Could you try with the new dev build 52.0.2743.19? There was a regression in M52 (a different issue) and I merged in a fix for it last week: https://bugs.chromium.org/p/chromium/issues/detail?id=590376

Yep, verified it works on 52.0.2743.19
