Pull request overview

This PR fixes a MySQL connection error that occurs during deployment when Django management commands (specifically make pull_translations) attempt to evaluate a waffle flag at import time before the database is available. The fix wraps the waffle flag check in a try/except block to gracefully handle database connection failures by defaulting to False.

Key Changes:

Version bump from 1.0.1 to 1.0.2
Added exception handling around ENABLE_GAMES_XBLOCK.is_enabled() to prevent deployment failures when the database is unavailable
