Remove fwapg function workaround when smnorris/fwapg#189 is fixed

[NewGraphEnvironment]

Problem

fwapg db/create.sh does not load FWA_SlopeAlongInterval, FWA_SegmentAlongInterval, or FWA_StreamProfile into whse_basemapping. Filed upstream: smnorris/fwapg#189

Our docker/load.sh currently works around this by loading the SQL files after create.sh runs. This workaround should be removed once the upstream fix is merged.

Current Workaround

# In docker/load.sh after create.sh
$PSQL -f sql/FWA_SlopeAlongInterval.sql
$PSQL -f sql/FWA_SegmentAlongInterval.sql
$PSQL -f sql/FWA_StreamProfile.sql

Resolution

Remove the workaround from docker/load.sh once smnorris/fwapg#189 is fixed and we update our local clone.
