Update group creation URL so it is always unique and does not generate an error
Currently, if a user creates a group with a name that has already been taken they are hit with a large error. This is a disruptive experience to the user, if they update the group name, it does not update the URL which keeps the error active, the user must manually adjust the group URL to clear the error.
As a user creates a group name we should create URL with that name and if the URL is taken we should automatically add random numeric values to the end of the name to ensure the error does not occur. If a user updates their group name on this page it should actively update the URL.
