Fix in Java>>flushClasses: do not use Smalltalk>>removeKey:
The problem is that it removes an entry in VM global list to which
stc-compiled static variables for globals point to (so-called
inidirect-globals). The entry is then used to update pointers
after scavenge. Therefore, after flushing Java classes these
indirect globals are no longer updated after scavenge, which
leads into funny sefaults (or inyto storing of survivors).
This commit should fix this problem.
