Does the change fix UDIG-1974?

Verified ✔️ that it works fine on windows, project-files (*.umap) are deleted. I'm wondering about log-entries for a deleted map, if it was created within the same session:
!ENTRY org.locationtech.udig.project 1 0 2017-08-23 10:56:37.662
!MESSAGE Not saving file://<path-to-workspace>\project.udig\Map.umap empty contents

Is it worth to have feedback like this or does it makes sense to avoid this logging-entry to avoid confusions?

I would say that UDIG-1974 is more related to locationtech-bug-166 which is addressed by pull request #235.

Concerning the logging I do not think it is completely useless. It is logged at INFO level and may also occur in the case a new project exists without a map or other resource beneath. I opt for keeping it as is.
