$(this.promiser) not expanded in edit_template

Hi,

I think I found a bug:

"/var/lib/cobbler/snippets/yum_repo_cleanup"
comment => "Add myself as yum repo server into snippet $(this.promiser)",
edit_template => "$(this.promiser).tpl",
classes => result_classes,
handle => "cobbler_files_yum_snippet";

yields:

cf3> .........................................................
cf3> Promise's handle: cobbler_files_yum_snippet
cf3> Promise made by: "/var/lib/cobbler/snippets/yum_repo_cleanup"
cf3>
cf3> Comment: Add myself as yum repo server into snippet /var/lib/cobbler/snippets/yum_repo_cleanup
cf3> .........................................................
cf3>
cf3> -> Using literal pathtype for /var/lib/cobbler/snippets/yum_repo_cleanup
cf3> -> Handling file existence constraints on /var/lib/cobbler/snippets/yum_repo_cleanup
cf3> -> Build file model from a blank slate (emptying)
cf3> !! Unable to open template file "$(this.promiser).tpl" to make "/var/lib/cobbler/snippets/yum_repo_cleanup"

It is clearly visible that the variable is expanded for the comment, but not for the edit_template. And it would be nice to detemine the template name directly from the promiser.

Cheers,
Sven
