Fix "Grant should not exist" errors.
...
This is done by making sure that when empty() is called on a context,
the grants Arc will be replaced with a new unused Arc, hence
decrementing the refcount. Previously this was only done when the
context was actually reaped, but since there is no guarantee as far as I
am aware about when this must happen, the grants could be completely
leaked, leading to the error.
