With updated specification of object related operation
we don't have this search attribute any more and we
should not use functions related to this attribute.
This commit breaks object service logic, however it will
be fixed later.

Now root and phy (leaf) filters work like flags. They work with
any matcher and any value. So meta-storage sets `true` value for
all root and phy objects and puts them into separate bucket.
We also do not work with inversion anymore, so it either added
to the bucket or not. We don't need to store both options.
This is the reason `selectAll` function is changed a bit. Now
it performs some low-level parsing from primary bucket and root
bucket.
