oox smartart, org chart: implement support for hierBranch conditions

The relevant part of the layout is the <dgm:layoutNode
name="hierChild2"> element that has a <dgm:choose> with two branches:

<dgm:if name="Name34" func="var" arg="hierBranch" op="equ" val="std">
<dgm:if name="Name36" func="var" arg="hierBranch" op="equ" val="init">

The connectors were missing as we took the first branch
(ConditionAtom::getDecision() returned true if the arg was hierBranch),
even hierBranch on the parent layout node was set to "init".

With this, the correct number of connectors are created, previously all
employee connectors were missing. Their size / position is still
incorrect, though.
