Reproduce:

• Goto Edit view of any Report
• Remove the name
• Save

Expected:

• I cannot save

Observed:

• I can save

Context:
Reports without name cause some interesting things. While nothing breaks in the application, the user cannot click on the Report where he should be able to, e.g. in the list of Reports to navigate to the report view. So I think the easiest solution is to define that every report must have a name
