Title: 1.4.x fix location npe and containment direction semantics

the grouping of and's and or's was wrong, causing an NPE in cloudstack tests when investigating parents;
the direction of containment (input should be descendent of location) was wrong also, i think,
to judge by the description "locationEqualsOrChildOf";
code is now a loop rather than fixed investigation of 3 levels
