fix issue #131

updated combine_GVA_long and GVA_by_sector to dynamically pick the year
but not year_sector_table because of the NSE syntax it is using which I
plan to change - in this case I had to supress the year_sector_table
unit tests, which I would replace at somepoint anyway with tests using
the dummy data.
