[Bug] activityType "Buy" not auto-mapped in CSV import

Environment

Wealthfolio 3.7.0 (WF); Windows 10 x64 in UK.

Steps to reproduce

Use a "Test1" dummy account, "Transactions" tracking mode, GBP currency.

CSV import this file, using the Default template:

"Date", "symbol", "isin", "quantity", "activityType", "unitPrice", "amount", "fee", "account", "currency"
"2019-06-19 08:51:00", "ATT.L", "GB00BNG2M159",  "1052", "Buy", "16.1478", "", "95.89", "test1", "gbp"

What actually happens

I am prompted to map the "Buy" activityType from the CSV to WF Buy.

What should happen

It should auto-map as the names match apart from case.
