utils: Fix bug in deepCompare which would incorrectly return objects with disjoint keys as equal (#2586)

* utils: Fix bug in deepCompare which would incorrectly return objects with disjoint keys as equal

* Fix bugs in sync test

This test wrongly asserted that `initialSyncLimit` would be used to make a filter
It is used only for the initial sync inline filter, and not in POST /filter
