Original PR Body

Fixes #6019

BREAKING CHANGE: the default behavior is changed to converting the object-type columns in the given data frame first before creating a DH table from it. While this change would result in much more sensible column types in DH, e.g. String vs. PyObject for object type column with only strings, it however will break user code written to handle the PyObject type columns in the result table.
