PHP Warnings when courseshortname_pre or courseshortname_post

[mudrd8mz]

When courseshortname_pre or courseshortname_post (or both) is configured to an empty string, a PHP Warning like this appears:

PHP Warning:  explode(): Empty delimiter in .../local/template_import/lib.php on line 138

PHP Warning: explode(): Empty delimiter in .../local/template_import/lib.php on line 145

I believe the module should still work even with these values set to empty.
