Fixes #94 by replacing function getCovariateDataSubset #95

Fixes #94.

Somehow the function getCovariateDataSubset was misbehaving. This function was used in two places, where I added the subsetting logic directly.

NOTE: this removes the ability to retrieve results from DB storage. As far as I know we were not using this anyway, as we read all premerged results from an .Rdata file.

@bdemeulder With the latest results data (9 data sources), I do still get warnings from data.tables. I think because of the sheer size of the data. But at least the issue of duplication of demographics data should be solved with this fix.

I get the following error in the cohort characteriazation tab. The numbers have changed though, (from close to 60M rows down to 550K rows), so I guess your fix did that.

@bdemeulder Indeed. It seems there are two issues, one on the shiny side and one on the data side. This PR only fixed the shiny side of things
