Economy/treasury: No data found for any secondary market treasuries. Displays a blank chart.

[montezdesousa]

Description

Fixes #1946 which failed to display chart with secondary market treasuries data. I believe it was a detail on the name secondary data has in the source dataframe. Code looks for first capital first letter 'Secondary' or 'Nominal' type of treasuries, which is not in this format for the secondary type. Just lowercased both the column name and the type_string to be searched to work for both cases. Seems to have worked.
