Fix economy/fred start date

[jmaslek]

#2412

Fix starting date issue. Took out the if limit==-1 because limit has to be > 0

[deeleeramone]

This is what I'm getting:

2022 Aug 25, 21:05 Danglewood /economy/ $ fred -p MORTGAGE30US
Error: get_aggregated_series_data() got an unexpected keyword argument 'limit'

Error: not enough values to unpack (expected 2, got 0)

Pretty sure I am checked out of the right branch because when I checkout back to origin/main, I get the old output with the start date being ignored.
