proxy: fix backend leak with 2-arg mcp.pool()
When mcp.pool() is called in its two argument form, ie: mcp.pool({b1,
b2}, { foo = bar }), backend objects would not be properly cached
internally, causing objects to leak.
Further, it was settings the objects into the cache table indexed by the
object itself, so they would not be cleaned up by garbage collection.
Bug was introduced as part of 6442017c (allow workers to run IO
optionally)
