fix missing string cast causing deprecated explode call #31

As from PHP 8.1, passing null to an explode call is deprecated and causes a warning being persistent is syslog.

Source: PHP - Deprecated Features Example syslog entry: Deprecated: explode(): Passing null to parameter #2 ($string) of type string is deprecated in /usr/share/icingaweb2/modules/netbox/library/Netbox/ProvidedHook/Director/ImportSource.php on line 133

Fixed by adding string cast to respective explode calls.
