v8binding: Fixes use of wrapper-tracing at Database class.

No one is holding a Database returned by window.openDatabase, so
it doesn't make sense that Database performs wrapper-tracing to
Database::creation_callback_ as the Database itself may be gone.

Plus, the |creation_callback| needs to be invoked only once when
the database is first opened.  So, there is no need for a Database
to have a member of |creation_callbak_|.

This patch fixes the (mis)use of wrapper-tracing at Database class.
