Duplicated log entries in the Error log view

[iloveeclipse]

Originally (by mistake) reported as eclipse-pde/eclipse.pde#773.

Started latest 4.30.0.I20230927-1800 build, did pull from github and saw this duplicated session and duplicated entries:

The log file itself looks OK:

I've looked into the code, must be a "classic" MT issue, managing internal elements and groups looks like not properly synchronized, so we create & add two groups / add elements to wrong groups etc.

I will push a PR.
