Prevent NPE on backwards seek on Chunker

Ensure that a reset() is not immediately followed by a data member
access with a call to maybeInitialize(). Practically, this can occur if
an offset has progressed locally, but the remote indicates a non-0
committed size, and would always have thrown an NPE on a requisite seek,
proven with the accompanied test case.

Closes #10566.
