+ Crashes under IDBDatabase::closeConnection

+
+ Reviewed by Alexey Proskuryakov.
+
+ * Modules/indexeddb/IDBDatabase.cpp:
+ (WebCore::IDBDatabase::~IDBDatabase): Do the work of close/closeConnection without
+ actually calling those functions.
+ (WebCore::IDBDatabase::closeConnection): Protect the database so it's not destroyed
+ in the middle of this function's execution.
