mediawiki.inspect#dumpTable: fix broken FF workaround

In Ib45487d10, we changed to invocation of console#table from
'console.table( data )' to 'console.table.call( console.table, data )'
to force an exception on Firefox, which doesn't define console.table
but doesn't complain if you try to invoke it. It should have been
'console.table.call( console, data )' instead.
