Description
When pasing a non-null value as containing_face to ST_addIsoNode the function checks if the node is _really_ inside the mentioned face. When passing a null, the function figures out by itself. When passing 0, no check is performed !

I do confirm the bug, but couldn't find the time to produce a testcase for it. It doesn't seem an easy case, possibly affected by a bug in ST_Intersect or something like that.
Commit r8941 simplifies the code and fixes the bug for me.
The existing testcase (test/regress/st_addisonode.sql) was hard to understand so I rewrote it with r8942

Actually, it seems worst than that. The good value fails too! May be an invalid ticket, inspecting further…
