Title:
  Merger tree walk (with satellites) skips a node

Status in Galacticus: A Semi-Analytic Model of Galaxy Formation:
  Fix Released
Status in Galacticus trunk series:
  Fix Released
Status in Galacticus v0.9.0.gcc4.6 series:
  Fix Released

Bug description:
  When outputting a merger tree (and so presumably in other cases also)
  the merger tree walk can sometimes skip over a node. This is
  problematic since: a) the node will not be output and b) it can fail
  to be updated (e.g. in cases where histories are extended to the next
  output time at each output).
