luci-base: load luci preferences early

Follow-up to 315dbfc749

In order to look at any saved uci value, the luci config
must be loaded before we render the page, so we can determine
stored preferences, for things like table filter, without
encumbering all consumers of configurable elements to load
the luci uci configuration.

All (Table) elements extend CBIAbstractElement, so load
there.
