Remove redundant check for WebVR runtime flag.

The code checks both the runtime flag and the origin trial status, when
the origin trial check implicitly checks the runtime flag first.
Removing this antipattern will allow us to eventually mark the
inappropriate checks as private, and reduce inadvertent bugs.
