Packaged games do not display PlayerName correctly using Steam OSS

Packaged games do not display PlayerName correctly using Steam OSS. Does not occur in Standalone.

Test project attached. To test, package for Development > Win64. When run (with the Steam client open, or opened from the Steam client), the game will show the computer name rather than Steam name. In a Shipping build, the game will display "Player" instead (which is probably related to [Link Removed] ).

Reproduced in 4.10.1 and Main (CL# 2813452). Does NOT occur in 4.9.2; this is a regression.

1. Open a new blank project
2. Add the OSS information to the project's DefaultEngine.ini file: https://docs.unrealengine.com/latest/INT/Programming/Online/Steam/index.html#iniconfiguration
3. Create a new Widget Blueprint
4. Add a Text block
5. Create Binding for the Text
6. Add the following to the resulting function:

7. Create and Add to Viewport from the Level BP
8. Package for Shipping > Win 64
9. Run game from the Steam client

Result:
"Player" is displayed

Expected:
The Steam user's name is displayed
