mod_http_oauth2: Apply refresh token ttl to refresh token instead of grant
The intent in 59d5fc50f602 was for refresh tokens to extend the lifetime
of the grant, but the refresh token ttl was applied to the grant and
mod_tokenauth does not change it, leading to the grant expiring
regardless of refresh token usage.
This makes grant lifetimes unlimited, which seems to be standard
practice in the wild.
