Lotus Version

Repro Steps

1. Try importing a sector using SAAS API ('SectorReceive rpc method') that is sealed up-to SubmitCommit state.
2. SectorReceive will fail with an error seeds differ; Miner's log will print out a warning like this one:

WARN	rpc	go-jsonrpc@v0.2.3/handler.go:406	error in RPC call to 'Filecoin.SectorReceive': provided(9e4c4ca02f51a2bb6e0e10eadfb45aedb8f8e56647b744ce4a51f740ca77c963) and generated(e9f8a071b727a51dcf7156a9fce7161b22829ddf79fd80199f0a1f0b37227470) seeds differ:
    github.com/filecoin-project/lotus/storage/pipeline.(*Sealing).checkSectorMeta
        /Users/mladen/Projects/filmineio/lotus/storage/pipeline/receive.go:140

Describe the Bug

Lotus-miner performs a wrong check while importing a sector that is passed a waitseed phase. While sealing a sector Beacon randomness is used, but lotus mistakenly checks for Ticket randomness in sector import. Correct randomness is checked later during workflow, for example inside builtin-actors.
