[GNC] Minor silliness bugs

[David G. Pickett]

I run the latest gnucash from flatpak on Ubuntu 22.04 LTS Linux.  When I launch gnucash from my taskbar of favorites, it sends a notification to my top central bar menu that it is ready, when it is only ready to display a splash, and many additional seconds must elapse before all the XML is loaded into VM structures.  Maybe it should not bother, or wait until the app window is actually open (usually asking if I approve my scheduled transaction creation with a list of mostly unchanged folders or subaccounts, also silly, as yes, I approve of it not changing unrelated things).
