Fixes incorrect definition of layout for SeriesType

[kozlov-alexey]

Details: definition of underlying data type of Series was done from PyObject dtype only and didn't take into account layout of original array, as a result 'C' layout was always inferred, where the original array might have other layout, which breaks iteration with such columns.

Fixes #996.
