"Unsaved buffers aren't restored if there is no project folder added to the window"

Here's my progress for the issue.

This issue was noticed before:
 https://github.com/atom/atom/pull/9968#issuecomment-163959573
 "Untitled buffers are saved based on the open folders" (instead of at any time)

It seems like the cause is https://github.com/atom/atom/pull/9968/files

The test simulates "When the buffer has no path" by calling `atom.project.bufferForPathSync(null)`

An untitled editor is opened by doing `atom.workspace.open(null)`

The path of an untitled editor is undefined.
