src/output.c: skip painting output when session is not active

Browse source 
On switching to a console vt when an application is painting,
labwc produces a stream of log messages of the form
```
 `00:00:52.345 [ERROR] [../src/output-state.c:45] Failed to commit frame` lines.
``

This patch tries to follow the lead from the solution to this problem
in https://github.com/WayfireWM/wayfire/pull/2484.patch

As noted in that commit message, this patch depends on unreleased
patches to seatd (master) to work reliably, and there may be a a risk
of locking up the labwc if it is used with the seatd-0.8.0.

Check that the session is initialized (is not NULL) before checking it
is active.
