Loading other plugins fails when a plugin interacts with filesystem in red4ext/plugins/

[poirierlouis]

RED4ext: v1.24.3

I'm currently implementing a migration routine, moving from <game>/red4ext/plugins/RedFileSystem/storages to <game>/r6/storages. I recursively copy files to the new directory, and delete the old directory, without errors. However, next plugins to be loaded by RED4ext are ignored (no log about them + crash because ofc native definitions are not found by redscript). If I run again, routine is not triggered, and all plugins are loaded as expected. Migration routine is called within RED4ext::EMainReason::Load callback, after registering types.

Culprit should be when iterating over plugins and loading them at the same time.

I'll look into this and propose a PR to first discover/queue plugins and load them after.

Workaround: only copy directory, and remove it when Unload is triggered.
