Build/Test Tools: Ensure strict assertion in comment dir

[3kori]

• In comment/commentsTemplate.php
  Changed assertEquals to assertSame because the expected and actual values produce identical arrays.

• In comment/pingback.php
Tests_Comment_Pingback::test_pingback - Changed assertEquals to assertSame because the expected and actual values produce identical arrays.

  Tests_Comment_Pingback::test_pingback_no_ping_back & Tests_Comment_Pingback::test_pingback_error_response - Changed assertEquals to assertSame because the expected and actual values produce empty arrays.

• In comment/query.php
Test_Comment_Query::test_get_comments_for_post - Changed assertEquals to assertSame and cast the expected value ($post_id) from an integer to a string because the WP_Comment::comment_post_ID is a numeric string.

  Test_Comment_Query::test_orderby_meta - Changed assertEquals to assertSame and cast the expected value ($comment_id) from an integer to a string because the WP_Comment::comment_ID is a numeric string.

  Test_Comment_Query::test_get_comments_by_user - Changed assertEquals to assertSame and cast the expected value ($users) from an integer to a string because the WP_Comment::user_id is a numeric string.

  Test_Comment_Query::test_orderby_date_modified_gmt_should_order_by_comment_ID_in_case_of_tie_ASC and Test_Comment_Query::test_orderby_date_modified_gmt_should_order_by_comment_ID_in_case_of_tie_DESC - Changed assertEquals to assertSame and cast the expected array value ($comments) from an integer to a string because the WP_Comment::comment_ID is a numeric string.

  Test_Comment_Query::test_comment_query_object - Kept assertEquals because the expected and actual output give different object instances but the same values.
