device-manager: dont pass terminal as renderer device

Various bits of fall back code pass the terminal device
as the renderer device.  This is wrong, ply_renderer is
a graphical renderer abstraction.

This commit passes NULL in those cases, so each renderer
does what it's configured to do by default.
