Sketcher: Fix segfault when activating a tool in a different view

Browse Source 
=================================================================

When in Sketcher edit mode, a tool button is activated, while the view has been changing to view of a different type, it segfaults.

This commit checks the pointer of the view to ensure correct type before activation, and refusing to activate if not of the correct type.

fixes #10809
