Fix: Handle missing openhands_prs table in OpenhandsPRStore

When the enrich_user_interaction_data cronjob runs, it queries the
openhands_prs table. If the database migrations haven't been run yet,
this causes a ProgrammingError because the table doesn't exist.

This fix wraps the database query in get_unprocessed_prs() with a
try-except block to catch the ProgrammingError and log a warning
instead of crashing. This allows the cronjob to complete gracefully
even if the database isn't fully initialized.
