no-same-owner: refactor to use matchtask()

[nishipy]

A part of #2105.

This PR refactors the no_same_owner rule and resolves the following problem. Please refer to #2105 (comment).

• currently uses matchplay() with custom match methods: handle_play(), handle_playlist(), handle_task().
• like no-loop-var-prefix this also misses rescue and always.
• the handle_*() and matchplay() methods should be condensed into a single matchtask() (handle_unarchive() and
  handle_synchronize() would probably stay as they are)

That is a beautiful refactoring. The rule is much clearer now, and it reuses the ansible-lint primitives. Thank you!
