Project file doesn't contain last version of SQL tab content (previously saved)

Details for the issue

What did you do?

I create a project and I open or create some SQL file and fill it with somes queries and I save the project. I modify again the SQL file and I save again the project. When DB browser crashed (yes it happens often), I reopen the project and :
1 - the open tabs with my previous SQL file and not linked to the real file on the harddrive anymore
2 - the content of the tab does not correspond to the last saved projet but seems to be an old version.

What did you expect to see?

When I save the projet, I would like to save uptodate tab content.

What did you see instead?

already explained higher
