coverage: record unary plus as refused until its result type is fixed

An unaliased unary plus over a literal, such as `+1`, now refuses with
SQ0009 instead of converting. Its converted result type, DECIMAL(1,0),
differs from Snowflake's NUMBER(2,0), so the unary-plus form moves from
matching to refused. The fix to the type and the name comes separately.
