Fixed a baaad bug in `WeakIdentityDictionary` w.r.t growing that may lead into value loss without noticing. This is bad expecialy for finalization registry where resources may be lost without being finalized. Imagine a following situation: 1. An instance of `WeakIdetityDictionary` (worse: `Registry`) is almost full. 2. Someone wants to add a new element to it, there's no space so `#at:put:` is about to call `#grow:` 3. GC kicks in and collecs more than one element. 4. `WeakIdentityDictionary >> grow:` is called to make space for new element. The problem is after step 3. the contents of the dictionary is (temporarily) invalid - there are two entries (at random positions) whose key is 1 (the corpse). Inherited `Dictionary >> grow:` would treat the corpse as regular key and map them to the same position in the hashtable - last wins, the previous values are simply lost without noticing. Even worse, in case of `Registry` instance, values (executors) are lost without without being sent #finalize so resource leaks. In an extream yet reproducible case this may lead into a loong uninterruptable lags if the dictionary is huge (500k entries) and most of is are corpses not yet taken away - the complexity of `#grow:` then degrades to O(n^2)! To fix this, we need to care for corpses while growing the dictionary and register their death.
