errors in seasonal recruitment and empirical wtatage

[Rick-Methot-NOAA]

Two issues were detected while working with Peter Kuriyama's anchovy model. One related to use of 2 seasons, and one related to use of empirical wtatage.
1.  recruitment in the Time_Series table is recruitment by area, not total recruitment.  They should be the same in a one area model. However, in a 2 season model with all recruits assigned to one season, a double counting occurs as the code loops seasons. The recruitment reported in this table gets accumulated for each season.
FIX by making the accumulation conditional on Settle_season. This was the case several releases ago, but got changed.
2.  Within the report.sso sequence to output biology, there were insufficient traps to prevent biology based fecundity calculations from overwriting fecundity as read from wtatage.ss. This occurred late in the output so few other items were affected by this overwriting. It was noticed when looking at SPR/YPR profile and the global MSY would also be affected. This issue may have caused when wtage storage was reconfigured in 3.30.17 or 0.18
FIX by adding appropriate conditional statements like:
if(WTage_rd==0) get_mat_fec();

@k-doering-NOAA I think this fix warrants a redo of the 3.30.19 release. Sigh!

@kellijohnson-NOAA I checked hake and this issue seems not to affect it, but I thought it would be affected.

@Rick-Methot-NOAA , we can put out a "fix" version, as we have done in the past. It definitely seems important to get the fix out there!
