v3.0.0 - alpha 3 - 404 when editing a project

[spikefishjohn]

I made this project with the phat client and then started poking around in the webui.

When I edit the project in the webui i get a 404 from it trying to open a readme for the project.

Same happens on the GNS3 web UI version 3.0 so I think it assumes that by default the README.txt file should exist.
The change in the diff below partially fixes this 404 not found issue but if you open a project or create a new one I still can see on the console log until I add some text in the Edit Project / Readme tab and save it. Then subsequent project opening do not display the 404 not found error anymore.
