Fixes the flaky mutable_object_test (#44413)

Based on a local issue I resolved, I believe this commit should fix the flaky mutable_object_test in #44396. The header of the mutable object was not being explicitly initialized. In some cases, this caused deadlock due to a spinlock backed by garbage memory. This commit explicitly initializes the header, which should resolve the issue.
