Upgrading NxRM2 to NxRM3: privileges with white space in name do not maintain their name after upgrade

Problem description

If there are privileges in NxRM2 that have white-spaces in the name, when NxRM2 is upgraded, these privileges appear to be assigned a string of characters making them difficult to identify.

These assigned strings are visible via the API, they don't show in the UI.

Steps to reproduce

• install NxRM2
• create one or more privileges with spaces in the name
  • i.e 'This is a new priv'
• assign the new privilege(s) to a role and assign that role to a user
• upgrade NxRM2 to NxRM3 (as per this guide)
• run API /service/rest/v1/security/roles/ {role_name}

Expected behaviour
Even if privileges cannot not be migrated with white-space in their names, perhaps we should fill those gaps with '-' or '_' but at least the name is retained.

Actual behaviour
Random strings are assigned to the name of the privilege.

Example
In my example I have created a privilege in NxRM2 called 'This is a new priv' against all NuGet repositories.
This in turn creates x4 privileges:

• This is a new priv - (create)
• This is a new priv - (delete)
• This is a new priv - (read)
• This is a new priv - (update)

I've assigned this new privilege to a new role called 'this is a new role' and in urn assigned to a user (local user called 'user1').

I then upgraded NxRM2 to NxRM3 (3.32.0-03) and when I run the following API call for the role 'this is a new role', here is what is returned:

http://ubuntu:8082/service/rest/v1/security/roles/this%20is%20a%20new%20role?source=default

{
  "id": "this is a new role",
  "source": "default",
  "name": "this is a new role",
  "description": "this is a new role",
  "privileges": [
    "a2b3c9cf6dc",
    "a2b3c80afa6",
    "a2b3c00ee62",
    "a2b3c617980"
  ],
  "roles": []
}

Using our nexus-toolbox/security-tree script, I can see the following:

├ 🤵 user1
│   ├ 📂 this is a new role
│   │   ├ ▪ a2b3c9cf6dc (repository-content-selector) [Repository: *] [Actions: delete]
│   │   │   └ • Selector:  format == "nuget" && path =~ ".*"
│   │   ├ ▪ a2b3c80afa6 (repository-content-selector) [Repository: *] [Actions: edit]
│   │   │   └ • Selector:  format == "nuget" && path =~ ".*"
│   │   ├ ▪ a2b3c00ee62 (repository-content-selector) [Repository: *] [Actions: add]

│   │       └ • Selector:  format == "nuget" && path =~ ".*"
