Fix memory leak in the memory manager

There was a bug in Chunk::sweep() that would lead
to parts of the memory not being freed as it should
have been.

This happened when an object 'overflowed' into the
next index of the estendBitmap, where we then would
not correctly clear the extends bits.

Fixes performance degradation in qmlbench's
delegates_item_empty_jscreation.qml over multiple runs.
