Bug 2 in MHSampler

[datang1992]

@lileicc
This is another bug in the MHSampler (different from the last one).
MHSampler fails on the following example:

random Integer X(Integer i) ~ UniformInt(0, 3);
random Integer Y ~ UniformInt(0, 3);
obs X(Y) = 0;
query Y;

The reason for this bug is that BLOG could not properly update the CBN correctly when a new instantiation is constructed.

I donot think it is the problem of initial world.
Since initial world is from LWSampler.
