Subject: [PATCH 38/39] remote: read symbolic refs via
`refs_read_symbolic_ref()`
We have two cases in the remote code where we check whether a reference
is symbolic or not, but don't mind in case it doesn't exist or in case
it exists but is a non-symbolic reference. Convert these two callsites
to use the new `refs_read_symbolic_ref()` function, whose intent is to
implement exactly that usecase.
No change in behaviour is expected from this change.
