  Issue #1680159: unicode coercion during an 'in' operation was masking
  any errors that might occur during coercion of the left operand and
  turning them into a TypeError with a message text that was confusing in
  the given context.  This patch lets any errors through, as was already
  done during coercion of the right hand side.
