Resolves: fdo#77899 fax etc wizards don't start

Wizards should look for templates in Template_internal, not Template_user

...as only the former reliably denotes the share/template tree where the
wizard templates are stored.  (Presumably the latter defaulted to the former as
long as it wasn't explicitly set in the past, but is now always explicitly set
since 838b77f5f3d6d8fd98891e99a23ff78a6a357cb2 "Resolves: rhbz#1065807 use xdg
~/Templates for default Template location.")
