Avoid return and callArg* clearing each other's state (#2593)
Browse files Browse the repository at this point in the history 
* Add regression test for #2572

* Partially revert "fix returns does not override call through (#2567)"

This partially reverts commit 5fde5ae:
- we keep the tests
- revert to the old manual clearing of props

The clearing of callThrough has then been manually added to what I
deem are the relevant spots. Tests are unaltered.
