Can't run scene if no main scene assigned

[cbscribe]

Godot version:
3.0.1

OS/device including version:
Mac OS 10.12.6

Issue description:
"Play Scene" won't play a scene.
No output in the editor, but running from the command line gives:

Error: Can't run project: no main scene defined.

Steps to reproduce:

1. Make a new project
2. Add a node and save the scene
3. Press the "Play Scene" button - scene won't open
4. Make a second scene and assign it as the Main scene
5. "Play Scene" on the first scene works

Basically, no individual scenes will run unless a main scene is assigned.

That one's for me, probably a regression from my recent `main.cpp` or `ProjectSettings` fixes. 2018-02-26 7:39 GMT+01:00 Chris Bradfield <notifications@github.com>:

I can confirm that, and even add that it some times crashes Godot.
