words crash (assert in texttool)

[Dag Andersen]

Reproduce:
* Add a new page to have 2 pages
* Add a text shape
* Enter enough lines to more than fill the shape

KWRootAreaProvider::provide() returns a root area without an associated shape, 
hence assert in TextTool.cpp:1284

Att. patch adds a check for associated shape to avoid this.

I don't have full understanding of the logic so I do not know if this 
introduces problems.

Could somebody in the know commit if it is ok, or maybe find a proper solution 
:)
