Fixed memory bug: properly root repeated/map field when assigning. (#8639)
* Fixed memory bug: properly root repeated/map field when assigning.

Previously the protobuf extension would not properly root
memory from a repeated field or map when assigning to a
message field (see the attached test case).  This could cause
crashes if the repeated field is subsequently accessed.

* Add accidentally-deleted Ruby test.
