Update horzion::wsgi::apache for new apache module

A recent bugfix in the puppetlabs-apache module broke this module's
usage of vhost redirects. This patch updates our usage of apache::vhost
to use the new redirectmatch_dest parameter and pins the apache module
dependency to 1.2.0 so that the new parameter will be available.
