User relations activity - bi-directional issue

Hello,

I've been working with the most recent changes and integration with the User Relationship module, and encountered a bug, it appears as if the heartbeat_defaults_heartbeat_related_uids function doesn't always pull all the relationships; I created a type of friend, which requires approval and isn't one way, but the stream only worked one way.

After line 260 copied below

$uids[$account->requester_id] = $account->requester_id;

I added the following line:

$uids[$account->requestee_id] = $account->requestee_id;

I'm new to the code for this module; so I'm not completely sure of the exact cause of the issue, however this fix seemed to work for me. If this doesn't fully fix it, I hope it at least lets you work out the problem, and fix it.

Thanks for the great module,

Michael
