update-index: reduce scope of index expansion in do_reupdate
Replace unconditional index expansion in 'do_reupdate()' with one scoped to
only where a full index is needed. A full index is only required in
'do_reupdate()' when a sparse directory in the index differs from HEAD; in
that case, the index is expanded and the operation restarted.
Because the index should only be expanded if a sparse directory is modified,
add a test ensuring the index is not expanded when differences only exist
within the sparse cone.
