upload-pack: send refs' objects despite "filter"
A filter line in a request to upload-pack filters out objects regardless of whether they are directly referenced by a "want" line or not. This means that cloning with "--filter=blob:none" (or another filter that excludes blobs) from a repository with at least one ref pointing to a blob (for example, the Git repository itself) results in output like the following: error: missing object referenced by 'refs/tags/junio-gpg-pub' and if that particular blob is not referenced by a fetched tree, the resulting clone fails fsck because there is no object from the remote to vouch that the missing object is a promisor object. Update both the protocol and the upload-pack implementation to include all explicitly specified "want" objects in the packfile regardless of the filter specification.
