org-test: Fix <point> feature
* testing/org-test.el (org-test-with-temp-text): Fix point position.
According to the docstring, if the string "<point>" appears in TEXT
then the string "<point>" is removed and point is placed there. The
problem was that after string "<point>" was removed, the point
was *not* placed at the position of the removed text, rather, it was
placed one character before that position which is wrong. The reason
is that Emacs buffer position is a number started from 1, instead of
0, in other words, the value of `(point-min)' is 1 not 0. The problem
is addressed by adding 1 to the calculated position.
