Resolves: tdf#117612 truncate DateAdd("m",...) to last day of month
... instead of resulting in error because of roll-over not being set. Fallout from commit 6d424f07701bf26d8fb173563b567d5f097c33e2 CommitDate: Tue May 2 23:12:34 2017 +0200 Replace mouth-painted "inaccurate around leap year" rollover algorithm that does stricter checking but DateAdd() needs a lax checking with truncate to last day of month. (cherry picked from commit 40c9a129e5a53e6eadfe8ca80c98ccf7eda957f9) Conflicts: basic/source/runtime/methods.cxx Backported.
