Is this an error in UsersController?

[alexvkcr]

In UsersController, we have a function to define who can delete and it goes like:
`def delete_possible?(user)
if user.nil?
return false

  return false
elsif !current_user.admin?
  return false
else
  return true
end

end`

I think it is possible that users delete their own account but not other's so the first elsif should be
elsif user != current_user

[chargio]

Yes, I think that this is wrong,

It should take into account that one can only delete its own children or account

def delete_possible?(user)
    if user.nil?
      return false
    elsif user == current_user
      return false
    elsif !current_user.admin?
      return false
    else
      return true
    end
  end

1. Create tests
2. See that the are red
3. Fix it

@sergio-ocon @alexvkcr I'll open a new branch and start working on it asap. The fix will go in a new PR I suppose, right?
