Don't update CMS preview on a CMS redirect

Browse Source 
The CMS preview causes unnecessary browser processing by loading a URL
which should be considered "in transit" when a CMS redirect is set through
the X-ControllerURL HTTP header. The CMS history processing will
load this new URL, and cause a new preview URL to be loaded.

Fixes https://github.com/silverstripe/silverstripe-translatable/issues/158
