Item not found: Project[id=0] when creating a new item

[Nicklas Nordborg]

Trying to create a new item when no project is the active project can result in an error message:

Item not found: Project[id=0]

This happens for all items (software, hardware, protocol and array design) that have the option to add it as a project default item (see #1614). It seems like this functionality wasn't correctly implemented and only works if a project is active and the "Set as project default" options is checked.

• If no project is active the above error message is displayed when trying to save the new item
• If a project is active, the new item is made a project default item, even if the option is not checked
