Fix i18n: missing python domain's cross-references with currentmodule directive or currentclass directive. refs #1363

* node attributes 'py:module', 'py:class' is provided from environment (e.x. currentmodule directive is provided on previous line, not on node)
* Because translation nodes are parsed in independently, 'provided attributes by environment' are not exist.
* For a pending_xref nodes, all attributes of a translated xref node should be same as original xref node in current test cases.
* For the above reasons, I overwrite all attributes from origonal node to new translated xref node.
