Update filename in title after File -> Save As ...

[anytizer]

When you do File -> Save As, the old references should be completely handed to new file. And, hence, its name on the title bar too. Currently, old file name persists on the title bar.

I cannot reproduce this issue on Arch Linux + GNOME + ~~Wayland~~ X11?, the window title updates correctly after I save the project with a new name with Ctrl+Shift+S.

But if you open an existing project, and file save as new name, sometimes, the filename does not update in title bar, properly. I am in Windows. It may be due to time-lag, but still, frequently reproduced.
