GUI: Some names remain translated after changing the language (problem mainly in Safe Mode)

### Problem description

When I start FreeCAD and change the language, some items still have the language based on my system locale (Polish). I could then just restart FreeCAD and all items should be back in English then. But I can't do this in Safe Mode.

The following items are still translated when I switch from Polish to English on the welcome screen in Safe Mode:

Start page shortcut buttons:

Task panel's title (and menu also Model panel's, but it's the same in Polish as in English):

View --> Panels (panel names there, also in the right-click context menu):

Notification area:

I will add more if I find something else.

### Workbench affected?

Core (App, Gui,...)

### Steps to reproduce

If your locale is not English, start FreeCAD in Safe Mode and change to English

### Expected behavior

Everything is in English

### Actual behavior

Some names are still translated
