Bug: Inlinetask bodies begun with a link (or other invisible elements) are not folded correctly

[Anders Johansson <mejlaandersj@gmail.com>]

Hi,
I had an inlinetask that started with a link, like this:

**************** Inlinetask heading
[[file:filename][link desc]] some text. Some more text.
**************** END

It didn't fold on TAB. Looking into org-inlinetask-toggle-visibility I see

;; Inlinetask was folded: expand it.
      ((get-char-property (1+ start) 'invisible)

which is true for all kind of chars that are invisible I guess (even if 
the value of the 'invisible property is 'org-link)

A quick test showed that adding a test for if the hiding is "outline" 
worked:

;; Inlinetask was folded: expand it.
      ((eq 'outline (get-char-property (1+ start) 'invisible))

I don't know if this has any unwanted side-effects though. Or if this 
should be avoided for some reason.

This is using the latest org from git.

Cheers,
Anders Johansson
