Fix summary issues

* Add missing time conversion for month
* #9606: FIx wrong usage of function when accessing data from summary file
The result values are aggregated into the destination vector in RimSummaryCaseCollection::computeMinMax(), so make sure the vector is recreated per case.
* #9602 : Make sure the plot is updated correctly for "Time since simulation start"
* Move roundToNumSignificantDigits() to RiaNumericalTools
* Make sure the time axis is consistent when individual time range differs
