QHash/QSet - fix QHash::erase when the hash is shared

Before a call to erase on a shared instance would imply that the
item was removed from the shared data (i.e all instances)

This patch improves the behavior to detach and erase the item
specified by the iterator (i.e same behavior as QVector)

Since QSet uses QHash it improves QSet the same way.

QList - fix QList::erase when the list is shared

Before calls to erase on a shared instance would in release mode
imply that items were removed from the shared data (i.e all instances).
In debug mode it would assert.

specified by the iterator(s) (i.e same behavior as QVector)
