  [BranchProbabilityInfo] Remove block handles in eraseBlock()

BranchProbabilityInfo::eraseBlock() is a public method and
can be called without deleting the block itself.
This method is made remove the correspondent tracking handle
from BranchProbabilityInfo::Handles along with
the probabilities of the block. Handles.erase() call is moved
to eraseBlock().
In setEdgeProbability() we need to add the block handle only once.
