refs: move `refs_head_ref_namespaced()`

The function `refs_head_ref_namespaced()` is somewhat special when
compared to most of the other functions that take a callback function:
while `refs_for_each_*()` functions yield multiple refs,
`refs_heasd_ref_namespaced()` will only yield at most the HEAD ref of
the current namespace. As such, the function is related to
`refs_head_ref()` and not to the for-each functions.

Move the function to be located next to `refs_head_ref()` to clarify.
