[BUG] Task finished signal never emit within a Storage Task

[LazyDridri]

In storage_tasg.gd, task_finished is defined with data in parameters
In storage.gd, task_finished is emitted without data.

Therefore, it is never emitted

IMPORTANT NOTE

It is only for 3.X, it has already been fix for new version from what I can see
