[1.1.53] "Select new blueprint contents for blueprint" overwrites the blueprint even when not saved

[Soul-Burn]

"Select new blueprint contents for blueprint" and "Upgrade items and entities in the blueprint" automatically save the blueprint, even though escape/cancel is pressed, without clicking "Save blueprint" or clicking "E". This is confusing compared to right-clicking entities, changing name, icons or description that do not automatically save.

Steps to reproduce:

1. Create a blueprint
2. Right click the blueprint
3. Click "select new contents for this blueprint"
4. Select new contents
5. Press escape or X in the top right

Expected: Blueprint isn't changed

Actual: Blueprint now has the new contents, even though it was not saved

Similarly "upgrade items and entities in the blueprint" is immediately saved.
