Doing node_load in admin_paths_alter is wasteful and buggy

There is a function ideation_admin_paths_alter that does node_load just to find out type of a node. That is very wasteful (=slow) and also buggy - there are modules (such as SPS) that will implement node_load hook and call path_is_admin() which will result in calling ideation_admin_paths_alter, causing a nested loop.
