Fix ANR when opening project with searchbar focus

[tomasMizera]

Weird bug here.. When we were trying to set visible property of the entire project controller (MMProjectController.qml) to false while searchBar had focus, the app would freeze (ANR). I spent a few hours debugging and have not found anything interesting. I believe this is coming from Qt (most likely https://bugreports.qt.io/browse/QTBUG-123876) as it started to appear in Qt 6.6.0 and even more in 6.6.3.
Ideally, the best fix would be to have the MMProjectController instantiated dynamically when needed and not play around with the visible property. However, that would be a massive change for now.

Resolves #3027
