fix issue with conflicting action statements

This PR will address https://github.com/xoxys/ansible-later/issues/35.

Collected metadata will be temp. removed from the raw task dict before
passing it to Ansibles `ModuleArgsParser` class. After processing, the
metadata will be added back to the result dict.
