Clear label tabel without rechecking

Issue description

When a topic is touched the label is recomputed. Currently the label is recomputed, compared with the entry in the label table and if they differ the entry is deleted. But this is inefficient and causes problems because during the recomputation the label table is also refilled. It would be easier just to remove the entries and recompute them. This would reduce number of recomputations.

Developer comments

Reconsider this, since while it is superfluous computation, it saves writing operations.

Rejection comment

Omitting writing operations is good. When the store is using dobjects the label computation does not even touch disk.
