macos: Using macdeployqt on Xcode built project breaks notifications

For some reason an application that tries to show a notification cannot do it anymore if macdeployqt was run to it, and only if it was built using Xcode generator for cmake.

To reproduce:

• load attached example
• change CMAKE_GENERATOR from Ninja to "Xcode" in Initial Configuration
• re-configure
• build and run

First it should ask if you want to allow notifications and if accepted, it should show notifications just fine.

Now run macdeployqt on it and try to run it again. Notification is not shown anymore.
