Ancestors: CollectionsTests-dtl.211

Add OrderedCollectionTest>>testStreamContentsPositioning.

String class>>new:streamContents: optimizes performance by answering originalCollection in the case of a stream positioned to the size of its original collection. This fails if the stream has been repositioned backwards to its original length.

The optimization was introduced in Collections-ar.129 which merges Collections-ul.128 from inbox:

- introduced #new:streamContents: in SequenceableCollection class. It's like #streamContents: but if you know the size of the new collection this method doesn't copy the result.
- updated SequenceableCollection class >> #streamContents: to use #new:streamContents:, kept the original default size 100.
