Null Pointer dereference in PAMInitialMeans.java

[Machiry]

There is a NULL Pointer dereference in https://github.com/elki-project/elki/blob/master/elki/src/main/java/de/lmu/ifi/dbs/elki/algorithm/clustering/kmeans/initialization/PAMInitialMeans.java#L151.

This happens when the if condition i.e https://github.com/elki-project/elki/blob/master/elki/src/main/java/de/lmu/ifi/dbs/elki/algorithm/clustering/kmeans/initialization/PAMInitialMeans.java#L155 is never taken.

We have implemented our own distance computation algorithm in which the condition will never be taken.

Yes, the code assumes there is at least one finite distance value.
I will add an error message if this happens.
