[C2] Error creating a social group

[daniboygg]

Describe Trying to create a social group gives an error in the browser console, but no feedback is given to user

To Reproduce Steps to reproduce the behavior:

1. Login in Chamilo
2. Goes to Social network
3. Go to Social groups
4. Click on Create a social group
5. Fill in the data
6. Click on Add button

Expected behavior A social group should be created

Additional context The line where error happens is this https://github.com/chamilo/chamilo-lms/blob/master/assets/vue/views/usergroup/List.vue#L238, it seems that the form does not gather permissions correctly

I can't reproduce it now, it seems already was fixed.
