Fix File->Open recent showing old files

[KingRabbid]

Description

When working with multiple JMeter instances in parallel, in GUI mode, the Open recent files doesn't get updated in the GUI but it does behind the scene, in the registry/shared storage. So what ones believes it opens, actually leads to opening another file.

Motivation and Context

Open what one wants, not some random file; in current state, the feature is unusable.

How Has This Been Tested?

Manual testing, multiple JMeter GUI instances, in each open various files, check the "File->Open recent" being refreshed in all GUI instances.

I tested this (quite late I know) on linux it has not the wanted effect. The menu select event is routed to the new code, but it seems, that the prefs object has no knowledge of the changed values (yet?).

Did you test your stuff under Windows?

[KingRabbid]

Hi,

I'm working in both Windows 11 and Linux (WSL 2 with Ubuntu 20+ or Rocky 10+) and fix works fine.
I'm still on an older version of JMeter v5.6.3, maybe the difference comes from 3rd party libraries or Java version (mine is v11)?

[FSchumacher]

Well, no 3rd party libraries on my side. I tested it on current trunk with at least Java 17. So maybe the differences are coming from the newer Java version or from Ubuntu on WSL handling file syncs differently than a "real" ubuntu directly on bare metal.

Could you test the updated #6675 and report if it fixes your problem?
