wt-status-deserialize: fix crash when -v is used

Fix crash in `git status -v` by setting `des_s->repo`
to a non-null value.

Upstream changes to eliminate use of `the_repository`
added a `repo` field to `struct status`.  And calls in
`wt-status.c` to `repo_init_revisions()` were changed
to pass `s->repo` rather than `the_repository`.

The status deserialization code was not updated to
actually set `s->repo` before common code passed the
value to OID routines.

This caused a segfault when verbose output was requested.
