lca, waitForSubscriptionAndBlock: making added iface funcs pure virtual.

The new contract between plugin & contextkit is: when we call
waitUntilReadyAndBlock() on a plugin, it blocks for as long time as
needed and then emits the ready() signal. So, the empty implementation
doesn't make sense (no signal would be emitted).
