* lisp/mouse.el (context-menu-entry): Don't create menu for Help commands.

Browse source 
Help commands that describe keybindings call context-menu-entry bound to
a key.  This causes too much trouble when trying to build the context menu
in a temporary Help buffer that is not displayed in a window.
OTOH, there is no information in context menus useful for Help commands.
So `help-buffer-under-preparation' is added to filter out such calls.
