Default Group Memberships is broken if you edit it twice: comma separator is replaced by pipe (|)

If you write multiple groups inside Default Group Memberships of User Directory using LDAP, when you will edit it it will be broken because the comma separator is replaced by pipe.

Reproduce: write: "jira-users,jira-internal" inside, save and edit again, you will see "jira-users|jira-internal" and if you save the configuration you will break the configuration, which will affect the user database.
