ObjectLoader: Fix log regression.

[Om-Mishra09]

Description
This PR fixes a critical variable shadowing bug inside ObjectLoader.js that causes the application to crash instead of gracefully handling malformed JSON.

Inside ObjectLoader.load(), when JSON.parse fails, the error is caught by a catch ( error ) block. However, the block then attempts to call error( ... ) using the imported logger utility. Because the caught exception variable shadows the imported function, this triggers a TypeError: error is not a function, crashing the execution entirely.

Changes:

• Renamed the caught exception variable from error to e.
• Passed e.message to the logger so the actual syntax error is properly surfaced to the developer.
• Added a targeted QUnit test in ObjectLoader.tests.js to ensure malformed JSON is caught and logged without crashing.

All unit tests pass locally.
