aliases missing check for inputs/outputs confusion

[o-smirnov]

Put this into my recipe by mistake:

  inputs:
    source-ms: 
      aliases: [prep.source-ms]
      default: msdir/1729634772_sdp_l0-Jupiter-corr.ms
    dir-out-base: 
      aliases: [prep.dir-out-base]
      default: msdir

Mistake, because prep.dir-out-base is an output. But instead of an error, I get

While I'm fixing this -- note that aliases to multiple named file outputs should be allowed. The latter should be fixed along with #287.
