Please disregard the previous email that contains an incorrect fix
suggestion. I wish my first contribution was flawless.
Here is what's happening.
git-filter-branch let git-update-ref -d verify that the value for $ref
matches $sha1.
However, when $ref points to an annotated tag that is being deleted,
that verification fails because $sha1 is the commit underneath.
I think there are two possible fixes:
1) either make git-filter-branch dereference annotated tags and do
the verification itself then use the two arguments version of git
update-ref
2) in the case of an annotated tag, pass another <old value> to git update-ref
Please find below a patch that implements solution 1). Please note the
patch doesn't contain a unit test for this situation as I wasn't sure
how to provide one. Yet I tested it on the repository I'm working on.

Subject: [PATCH] git-filter-branch: support annotated tags deletion
git-filter-branch let git-update-ref -d verify that the value for $ref matches
$sha1. However, when $ref is an annotated tag being deleted that verfication
fails because $sha1 corresponds to a commit object.
Instead of asking git-update-ref to verify values actually match, dereference
$ref ourselves and test against $sha1 first. Then invoke git-update-ref with two
arguments.
