[JS] Table.from fails for zero-item Lists, FixedSizeLists, Maps. ditto Table.empty

[asfimport]

deserializing zero-item tables (as generated by Table.empty or, in this case, pyarrow.Schema.serialize) with a schema containing a List, FixedList or Map fail due to an unconditional 

new Data(/* preceding parameters */ buffers, [childData])

statement, the childData parameter resolves to  [undefined] rather than the desired [].
