app: improve GimpTool::button_release(GIMP_BUTTON_RELEASE_CLICK) 

when a click is detected by gimp_tool_check_click_distance(), only do
a motion() back to the button_press() coordinates if there has been a
motion at all since button_press(). This should not change any tool's
behavior, it's only an optimization to keep tools from doing useless
work.
