MSG generation creates invalid stream

I've found another MSG generation problem with Aspose.Email (5.3).

At customer – a lot of messages don't actually contain any named properties:

Stream: __substg1.0_00040102

Size: 0

However, the same message exported from PST via Aspose results in this:

Stream: __substg1.0_00040102

Size: 1

And the content of this stream:

0000000000: 00                     

I've included a sample message and the PST file that the message was exported from via Aspose.Email component for you to check.

Our processing library checks MSG violations and fails on this.

I guess there are more than one problem with NamedProperty storage - (1 bug there already – EMAILNET-34810 - not aligned entries on 4 byte boundary). Could you please make sure this violation is fixed along that other bug.
