Ensure modal rendering works.

The modal rendering setup has changed such that no
view is passed around, so no ViewId is set either.
Since for a modal renderer we don't really have to
worry about potential other views we will just ignore
the check for viewport id.

The old check resulted in no camera data being sent to
Cycles, which was visible as a complete black render
result.
