After creating a new project and confirming to add program- and sql-windows PL/SQL Developer shows a weird behavior regarding the actual items added to the created project.

Steps to reproduce:
1. Create and save SQL file (alternative scenario would be saving after 2. or 3.)
2. Add some select statements to the SQL file accessing different tables
3. Run all selects with F8
4. Create new project via "Project > New"
5. Check "Only add Program Windows and SQL Windows" and confirm "Add opened items to project?"
6. No changes in Project Options, just confirm new project with "Ok"
7. Select "Project > Project Items"

Observed behavior: The table of the last run select (3.) is displayed as the only project item. In rare cases the table of one random select of (3.) was added as project item, but always just one table. SQL File is missing as project item.

Expected behavior: The created SQL file should appear as project item. No tables added as project items.

Using PL/SQL Developer Version 15.0.2.2054 (64 bit) on fully patched Windows 10 machine.

I can indeed reproduce this. We'll fix it!
