Description:

When the option "Allow Special Characters in Room Names" is enabled and turned on, it can occur that the name of a newly created channel or group doesn't correlate with the name that was actually passed by the user / API who created the channel.

Steps to reproduce:

1. Make sure "Admin UI" → "Layout" → "User Interface" → "Allow Special Characters in Room Names is set" to true
2. Create a new channel with the name d4edcce7-a6a8-457e-94c4-0b2d43cd51b8
3. Notice the incorrect name of the channel d-4-edcce-7-a-6-a8-457-e-94-c4-0-b2d-43-cd-51-b8

Expected behavior:

Admin UI → Layout → User Interface → Allow Special Characters in Room Names: "false"

{
        [...]
        "name": "d4edcce7-a6a8-457e-94c4-0b2d43cd51b8",
        "fname": "d4edcce7-a6a8-457e-94c4-0b2d43cd51b8",
        [...]
}

Actual behavior:

Admin UI → Layout → User Interface → Allow Special Characters in Room Names: "true"

{
        [...]
        "name": "d-4-edcce-7-a-6-a8-457-e-94-c4-0-b2d-43-cd-51-b8",
        "fname": "d4edcce7-a6a8-457e-94c4-0b2d43cd51b8",
        [...]
}
