#1270: Load global user settings outside project

The changes look useful to prevent the Bug from occurring in the feature. Nice Work 👍

@ducminh02 thanks for your PR. You did a great job to implement this story 👍
I found some things you missed out. Do not worry too much, since one needs a lot of deep knowledge of IDEasy to understand the coherences but with an end user test via native image this would have been revealed. I plan a KT session with the team about this for the next future...

@ducminh02 thanks for your improvement. Excellent. Now everything should work perfectly correct. 👍
Ready for merge.
