<h3>Log Message</h3>
<pre>Don't prime groupmeta cache in BP_Groups_Group::__construct()

groups_get_groupmeta() now uses the core API functions. get_metadata() works by
priming the cache with *all* object metadata when requesting any piece of
metadata for that object. This means that, instead of pre-fetching groupmeta
when instantiating BP_Groups_Group, we wait until it happens in get_metadata().
At best, this can help us to avoid pre-fetching a meta cache that will not be
used.
