Before this commit, switching websites with custom domains was not
properly done: the client action should redirect to the custom domain if
there is one, instead of only redirecting the iframe.
The redirection was not correct for the "go to website" buttons either:
in that case, the url was incorrectly generated for the redirection (the
custom domain was passed in the path parameter of the client action).
See merge commit for more information.
