[devtools] "fix" boundary condition for autofill

maxvalue in an IntervalBoundConstraint is inclusive.  If the min and max
values happened to coincide, we would call random.choice on an empty
list, which it didn't like.

This is still broken in the case of BoundaryConstraint('>', minvalue),
as we assume the minvalue is in the range, but that's something for
another time.
