Router: account for blinded path fee, etc on first_hop<>intro hop add

This previously led to a debug panic in the router because we wouldn't account
for the blinded path fee when calculating first_hop<>intro_node hop's available
liquidity and construct an invalid path that forwarded more over said hop than
was actually available.

This also led to us hitting unreachable code, see direct_to_matching_intro_nodes
test description.
