Changing the name of a role is not possible

[pallinger]

Steps to reproduce the issue

User-created dataverse roles can (in theory) be edited (pencil icon on screenshot) on any dataverse or dataset permission edit screen:

You can change the name (you may see it is misspelled) in the dialog box:

But then you get an error.

Which version of Dataverse are you using?

v. 6.1 with some minor modifications, but those do not concern with the role/permission system.

Are you thinking about creating a pull request for this issue?
We may try to address this, but we do not know when we will have the time.

Currently, this can be worked around with a direct SQL query:
UPDATE dataverserole SET name='' WHERE alias = '';
