fdo#63311: Unable to delete text from Shape

[Muthu Subramanian K]

Hi,

I have attached a patch for fdo#63311 with this mail.

Basically, the patch makes sure there is no NULL text, but instead uses 
empty_text.

[empty_text seems to be the initialization text for the shape while NULL 
seems to be applied when the user removes the text]

I am not sure if this is the right fix - or should we be fixing the code 
which assumes text to be not null, please?

[I remember vaguely David removing the null places - not sure if this is 
related or if it was for something else]

Thanks a lot!
