Setting org-superstar-remove-leading-stars to 't' corrupts headings

[hpgisler]

Observed behavior

sample org file:

** heading 1
** heading 2

if point is placed on heading 1 and then C-<ENTER> is pressed this leads to the following result:

** heading 1
*** 
* heading 2

Expected Result

** heading 1
** 
** heading 2

How to Reproduce

1. start: emacs -q
2. (load "org-superstar.el")
3. (setq org-superstar-remove-leading-stars t) ;; <-- that's the culprit, if nil, it works correctly
4. (org-superstar-mode)
