Fix initMountPoints to set usersSetup earlier
Fix initMountPoints to set usersSetup earlier

This is needed because in some cases like LDAP, the user manager itself
might trigger avatar updates which would internally also call
initMountPoints with the same user. This could cause the same user to
be setup twice, and in some sharing situations could cause recursive
deduplication of shares by adding "(2)" every time.
