Creation of a Virsat diagram is causing a NullPointerExpcetion if the diagram name has a space in it

[dellerDLR]

Describe the bug
If a Electrical Architecture or State Machines Diagram is created, which name has a space in it, a NullPointerException is thrown:

To Reproduce
Steps to reproduce the behavior:

1. Right click on the documents folder on a ProductTree or ConfigurationTree
2. New > Other... >VirSat > Virsat Diagram
3. Enter a name with a space like "another test"
4. Select Diagram Type "interfaces" or "stateMachines"
5. Finish

Expected behavior

The Diagram editor should open without a NullPointerException.
