ThingTemplate: Add null check for ModuleData after creation

[seer-by-sentry]

Fixes CLIENT-RP. The issue was that: INI parsing attempts to load an unregistered module name, causing ModuleFactory to return NULL, which is immediately dereferenced.

• Added a null check for the ModuleData pointer returned by TheModuleFactory->newModuleDataFromINI.
• If the ModuleData pointer is null, a debug crash is triggered with detailed information about the error, including the line number, filename, module name, and thing template name.
• An INI_INVALID_DATA exception is thrown to halt further processing.
