[Unknown Mod][Adventure Map] Indicate “already visited” in the right click info of the magic garden when it visually indicates that it is “empty”

[LeHerosInconnu]

Indicate “already visited” in the right click info of the magic garden when it visually indicates that it is “empty”.

In the example, the blue hero visited the magic garden and therefore emptied it of its contents.
This is visually indicated by an empty magic garden (without the leprechaun).
Although no hero belonging to the green player visited the magic garden, it is considered to have already been visited and the right click info is updated.
