Merge 2706080bc8 into 20354e7c11

Workaround for an issue after upgrading from WiX Toolset v3 to v5 where the previous
version of Dangerzone is not uninstalled during the upgrade by checking if the older installation
exists in "C:\Program Files (x86)\Dangerzone".

Also handle a special case for Dangerzone 0.8.0 which allows choosing the install location
during install by checking if the registry key for it exists.

Note that this seems to allow installing Dangerzone 0.8.0 after installing Dangerzone from this branch.
In this case the installer errors until Dangerzone 0.8.0 is uninstalled again
