Disable WAL checkpoint from the finalizer

If SQLiteConnection.close() is called from the finalizer, disable WAL
checkpoints.  WAL checkpoint can be IO intensive and can cause the
finalizer timeout to expire.  Three things to note:

  1. The finalizer is invoked only if the application has failed to
     explicitly close the database, which is, itself, an error.  This
     change has no effect if the database is explicitly closed.

  2. Even though there is no checkpoint, the WAL file remains intact
     and no data is lost.

  3. The effect of not checkpointing is the same as if the application
     had crashed or had been killed.  Which happens all the time.
