Fix LT-22346: Crash occurs using lexicon edit popup

[jtmaxwell3]

This fixes https://jira.sil.org/browse/LT-22346. Insert Part Relation wasn't closing because it expected DialogResult.OK, but we were using DialogResult.Retry for "Create and Edit". I also changed SendMessage to PostMessage to give the Insert Part Relation dialog time to close before the popup opened.

Src/LexText/LexTextControls/InsertEntryDlg.cs line 1352 at r1 (raw file):

					if (DialogResult == DialogResult.Retry)
					{
						m_mediator.PostMessage("JumpToPopupLexEntry", m_entry.Hvo);

Was the change from SendMessage() to PostMessage() a necessary part of the fix?
The reason I ask is because we are in the process of replacing most of the mediator functionality with Pub/Sub functionality, and SendMessage() calls are an order of magnitude easier to replace than PostMessage() calls.
