[O] [BUG] Convert heading with no content to item fails

[Adrian Bradd]

Hello,

On master (commit: 51b339105), attempting to convert a blank headline to an item with `org-ctrl-c-minus' removes the space after the * and org no longer recognizes it as a heading.

I believe this issue originated in commit 69c5b6c99. Some code was added to strip metadata during the conversion in `org-toggle-item' with `org-heading-delete-metadata'. '(org-set-tags-to nil)' is used to strip tags which in the case of the blank heading results in `(delete-region (match-beginning 1) (match-end 1))' being called.

`delete-region' in this case removes the space immediately after the star/s in the blank headline which puts the line in a state that org doesn't consider a headline.

Replacing the removed space following the * or preventing its removal would remedy the issue, but I wasn't sure where to implement this. Didn't want to make the change in `org-set-tags-to' for fear of downstream effects.

Cheers,
