Local vs Remote cred check fixes
Do not check for remote cred in LOCAL_ONLY case, since we are instructed to
specifically not check with the proxy. However, still fall back to remote
with cred_store, since it may simply indicate what ccache to use to store the
remote credentials reference and not where to fetch the credential from.
