Split and merge of replies breaks topic/reply order when replies precede topic

[jmdodd]

When an older topic is merged into a newer topic, the newer topic is backdated to 1 second before the post date of the older topic.

However, this backdating does not occur in the destination topic when a string of older replies is split and merged into a newer topic. This results in an unordered display case where the older replies, then the topic, and then the newer replies are displayed in the topic thread.

Suggested fix: backdate the destination topic for the split and merge case if necessary (see bbp_merge_topic_handler(): Date Check).

(In [4362]) Topic Split:

• When splitting a topic off into an existing topic, use the same kludge from topic-merge, and rejig the post_date by 1 second.
• This keeps topics and replies in the correct order after splitting part of a topic, into another topic.
• Props jmdodd.
• Fixes #2015.

Fixed for 2.2.
