cluster-creator-login.sh: always assign user to globalrole even when user exists
I had done this commit a while ago (July 1st).
I don't remember today what lead me to do it, but it seems like a relevant robustness improvement: if, when the script is first ran, the user creation succeeds but the role assignment fails, then with this change the role assignment will be done on the second run.
