"New Vorto Project" wizard generates: IllegalArgumentException: Path for project must have only one segment.

Steps to reproduce:

• Vorto 0.10.0.M2, Eclipse: Oxygen.3a Release (4.7.3a)
• In Vorto Model Project Browser, choose "Add Vorto Project"
• In the wizard dialog, select the project name and delete it (for example with backspace)
• Check the error log view, there is:

java.lang.IllegalArgumentException: Path for project must have only one segment.

Is this exception expected in this scenario? To me, we should not have it, because there is an error message in the wizard dialog: Project name must be specified.

You are right, This error log should not appear in log as it is handled in the Wizard already.
