Avoid never-ending growth. When adding more entries, it now deletes the first entry in the list, which is the oldest added entry still held in memory. I decided to avoid a Least Recently Used concept as I suspect with a list with this many entries most entries have not been used, and we don't save the timestamp of recent use anyway. The net effect might (no matter what) be that the removed entry might feel a bit "random" in the eyes of the user. Verify with test 1669. Reported-by: Geeknik Labs Fixes #21183 Closes #21189
