PixelPaint: Properly transfer active tool to editor on tab close

Browse source 
Previously the code assumed that the active tool had a reference to
the old editor, which is the only way we had to check if it is
active without having a reference to the editor. However, when a
tab in PixelPaint is closed, the editor is destroyed, so the `WeakPtr`
in a tool referencing the old editor is no longer valid.

This made it so that if you closed a tab, the tool would appear to be
selected in the ToolBox, but the editor would not know about it at all.
