If I run org-tree-to-indirect-buffer twice with a prefix argument, I get a
buffer that's too narrow and omits the text of the last heading in the
tree. In this state, tree operations can result in data loss.

To reproduce, open a file containing the following data:

* I
** A
** B
* II

Follow these steps:

1. S-tab to fold everything.
2. With point on the "I" heading, C-u C-c C-x b to open an indirect buffer.
3. With point on the "I" heading in the new buffer, C-u C-c C-x b to open
another indirect buffer.

The buffer created in step 3 will look like:

* I
** A
**

Note that the text "B" is missing from the last heading. Expected behavior
is

* I
** A
** B

4. With point on the last, blank heading in the buffer created in step 3,
M-up to move the heading. The heading will disappear, resulting in:

* I
** A

If you write the file, it will look like this:

* I
** A
B
* II

Expected behavior from steps 1-4 is:

* I
** B
** A
* II

I can reproduce on both the version of org that shipped with emacs 27.2,
and with the gnu elpa package.

Emacs  : GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version
