Improve "Asset import did not unload metadata path. This will leak memory." Error

Unity Engine

Please include the path of the asset that is causing this error.

Knowing which asset is causing it would allow me to try to reimport or copy/paste the asset to a new project to see if it can be reproduced.

Without knowing the path it’s difficult to find the asset in an existing project, due to having many assets already.

Edit: The path is printed to the editor.lo. Would be used to have in the actual error message that is printed to the Unity Debug Console window nonetheless.
