Fix outliner/selection updates when selecting in the 3D view

The checks for calling outliner flushing didn't account for
entering pose mode for the first time or that pose-bone selection
can also change the object selection.

Resolve by recording what changed and refresh accordingly.

Also de-duplicate calls to DEG_id_tag_update.
