unshelve: delete shelvedstate after a successful unshelve --continue

`unshelve --continue` was preventing the deletion of `shelvedstate` on
a partial `unshelve`. Ideally, `shelvedstate` should be deleted after
a successful `unshelve`. Now, the behavior of `unshelve --continue`
will be as follows in interactive mode:

1] The user tried to `unshelve` changes interactively but, ran into
 conflicts.
2] They resolved the conflicts and triggered `unshelve --continue`
 but, unshelved changes partially.
3] Now, on trying to do `unshelve --continue` again will abort as
 the last `unshelve` was successful and we are deleting the
 `shelvedstate`.
4] If they want to unshelve the remaining shelved change, they
 need to trigger `unshelve` without `--continue`.
