Accept empty tsquery in binary input.

Browse Source 
tsqueryrecv() calls findoprnd() even when the input has no query
items, so it fails on an empty tsquery, which is legal data.
This breaks, for example, binary COPY of a table containing an
empty tsquery.

Skip the operand walk for an empty query, as parse_tsquery() does.
