Short Description: Fixed "run-range" start date, was wrong after stopping run.
Bug Number: 5139
Release notes (y/n): Yes (for 6.1.1)
For Release Nums: 6.1.1 and 6.2

Gnats 5139: Stat Slot Filter Range: run-range wrong after stopping run.

This had the same cause as Gnats 5104 (open slot dialog and plot dialog).

In calls to RunInfo::getStartDate(), use the variant of that method which 
takes a bool parameter, 'getRunInfoDate', and pass in 'true'.  (Otherwise
the 'resumedStartDate' is returned). 

This change is made in the following files and functions when the range
mode is "Run Range":

---------------------------
Sim/TableSlot.StatFns.cpp
---------------------------

  static okstat filterInput(TableSlot *targetSlot,
                          SeriesSlot *inputSlot,
                          std::vector<ValueInfo> &filteredData)

---------------------------
Sim/TableSlot.StatUtils.cpp
---------------------------

  TableSlot::StatFnData constructor;
  QString TableSlot::getStatFnFilterString() const;
