In multisite environment, objects containing "/" in the name are not synced

Steps to reproduce:
===================

1. Create new object on primary zone in "test-sync-bucket" callend "obj-no-slash"

2. Object is synced correctly

From secondary:
$ python3 list_bucket.py $s3_creds test-sync-bucket
obj-no-slash

3. Create object with slash called "object-/with-slash" on Primary

4. Object is not replicated.

From secondary:
$ python3 list_bucket.py $s3_creds test-sync-bucket
obj-no-slash

but the object is present on the Primary:
$ python3 list_bucket.py $s3_creds test-sync-bucket
obj-no-slash
object-/with-slash

Note: same happens if the object is created on the secondary, it will not be replicated on the primary

Expected result:
================

"object-/with-slash" is replicated correctly
