Detection issues under Chrome

[peakwinter]

Expected Behaviour

While using Chrome, the URI scheme detection should work properly from the first page load.

Actual Behaviour

While using Chrome, the URI scheme does not appear to be detected until the user clears a "Ring presence is unknown" alert at least once.

Steps to reproduce

• Click "Ring Me" after a first load.
• The download page redirect prompt appears.
• Click on Cancel.
• Ring opens successfully anyway.

Notes

At the point where the alert window is opened, this.isRingSchemeSupported() returns false. But on subsequent attempts in the same browser session, it returns true. It's just this first run that either has a false detection or doesn't prevent the window from launching when the user clicks Cancel.
