fix classic ChildToParentMessage.hasExecuted

[DZGoldman]

This fixes two adjacent bugs in ChildToParentMessageClassic.hasExecuted:

1. ChildToParentMessages whose proper execution reverts throw in hasExecuted, when they should return false
2. ChildToParentMessages that use the classic outbox VERSION_NUMBER=0 throw since their revert message isn't handled ( v0 vs v1).
   Both bugs can cause status to return UNCOMFIRMED when it should return CONFIRMED
   E.g., see

This ensures all reverts that other than those caused by improper inputs return false.
