Fix the link.

Description (updated)
-------

We are using KCollapsibleGroupBox in Ark and stumbled upon a segfault in an autotest involving this widget (see backtrace [here](https://paste.kde.org/pwcohd64z)). It looks like QTimeLine::stop() gets called after KCollapsibleGroupBox is deleted. This causes QTimeLine::stateChanged to get emitted which then calls KCollapsibleGroupBox::updateChildrenVisibility() that causes the crash.

To see the crash, clone the newAddDialog branch of Ark and run the autotests.

This diff calls QTimeLine::stop() in the KCollapsibleGroupBox dtor if it is running, before deleting the d pointer.

Testing
-------

The autotests in newAddDialog branch of Ark pass with this diff.


Thanks,

Ragnar Thomsen
