Excel export column worked user is empty and username does not contain username

[Ronald Vallenduuk]

The title says it all: the worked user column is empty, and in username there's the users' full name. For reporting full name is better, for integration username is better. Can we just have both in the report?

[Andriy Zhdanov]

Worked User column is hidden now, as it is useless, because Username is the worked user. Username column has name only now, and Display Name column additionally has user full name.
