Fix missing Cursor close

        RowData result;

        waitForExpressionDB();

        String args[] = new String[] { Long.toString(index) };

        Cursor resultC = mExpressionDB.rawQuery(SQL_GET_ROW, args);

        try (Cursor resultC = mExpressionDB.rawQuery(SQL_GET_ROW, args)) {

            if (!resultC.moveToFirst()) {

                throw new AssertionError("Missing Row");

            } else {

                result = new RowData(resultC.getBlob(1), resultC.getInt(2) /* flags */,

                        resultC.getLong(3) /* timestamp */);

            }

        }

        return result;

    }
