Expression-with-no-value

Group-Object and properties made by expressions with no values

Group-Object may fail with NullReferenceException if input objects have a NoteProperty made by an expression with no value. It works fine in v2, so the issue was introduced by a later version.

A workaround, if applicable, is to change an expression so that it returns $null instead of nothing.
