bundlerepo: make secret revisions visible, if bundle bases on current local repo

Before this patch, "hg incoming" may not show the revisions in the
bundle, even though they are restored by "hg unbundle". For example:

    1. there are two secret revision: A and its descendant B

    2. "hg strip B" saves it into backup bundle

    3. "hg incoming" with backup bundle above doesn't show B, because
       parent of it (A) is secret and hidden

    4. "hg unbundle" with backup bundle restores B, though

This patch makes secret revisions visible at "hg incoming" , if
"other" is "bundlepeer" and it bases on current local repository.
