> metamodels for project org.xtext.example.mydsl".

Hello,
I try to reproduce this bug using the xtext project wizard.
I discovered that an ResourceExeption is thown if you create a
project with a name of a project already in workspace, but not imported.

Exception:
!MESSAGE org.eclipse.xtext.ui.util.EclipseResourceUtil  - org.eclipse.core.internal.resources.ResourceException: Resource '/org.xtext.example.mydsl/META-INF' already exists.

The applied patch will prevent this exception.
