[ASTextNode] Fix text node truncation (#1863)

Browse Source 
* Before truncate a text storage in ASTextKitContext reset the text storage to original value

* Fix ASTextNode tests

We should pass in the constrained size in both cases and the sizes should be the same. We adjust the calculated size in ASTextNode to be a bit narrower in the second case if we truncate again with the calculated size as constrained size it will truncate more and the resulting size will shrink.
