  Crash under SQLiteDatabase::~SQLiteDatabase

Reviewed by David Kilzer.

The crash was occurring because SQLiteStorageArea::handleDatabaseCorruptionIfNeeded()
was destroying the SQLiteDatabase object (m_database) but was failing to destroy the
potential transaction (m_transaction) and cached statements (m_cachedStatements), all
of which have a CheckedRef pointing to the database.

Update handleDatabaseCorruptionIfNeeded() to call close(), which clears m_cache,
m_cacheSize, m_transaction, m_cachedStatements and m_database.
