Hotfix of a crash with raft and one-layer object (#5652)

Browse source 
The problem is that PrintObject support generator is only run when m_layers.size() > 1, so one-layer object will skip it.
It apparently never worked, after recent refactoring (probably 8bfc986) it started to crash in GCode generator.
This commit fixes the crash, but not the problem. The raft is still not generated (like in all versions since 2.0.0 at least).
