Joshua Haberman 414e4142cd Sync sub-objects in PyUpb_Message_MergeFromString even when decode fails. 
In 'PyUpb_Message_MergeFromString', 'upb_Decode' may partially mutate or populate sub-messages on the parent message before failing with a decode error status. Skipping 'PyUpb_Message_SyncSubobjs' when 'status != kUpb_DecodeStatus_Ok' leaves stub sub-object wrappers unsynced in 'unset_subobj_map', causing duplicate keys in 'ObjCache' on subsequent access and leading to heap-use-after-free.

Move 'PyUpb_Message_SyncSubobjs(self)' before the decode status check in 'PyUpb_Message_MergeFromString' so any sub-message wrappers modified during decoding are synced properly.

Add 'testMergeFromStringDecodeErrorSync' to 'third_party/py/google/protobuf/internal/message_test.py' to verify that stub sub-objects remain synced and intact after a failed 'MergeFromString'.
