pkg/index: use IsDeleted in some of the search methods

1) Done in AppendClaims, PermanodeOfSignerAttrValue,
SearchPermanodesWithAttr, PathsOfSignerTarget,
and PathsLookup.

2) camtypes.Path.DateClaim is now a time.Time, and used
as such in Path search methods.

3) Added kvSignerAttrValue, kvPathBackward, and kvPathForward

4) More Delete tests. We probably want more cases, but that's
a start.

pkg/index: another delete test case

This test verifies that a permanode is still considered
deleted until all its deleters have been deleted.
