No error when using conditional expression without value

[Per Östlund]

This model does not give an error, it just fails to evaluate the conditional expression and removes it:

model M
  parameter Boolean b;
  Real x if b;
end M;

[Per Östlund]

Fixed locally, will commit once bootstrapping features are allowed in trunk.

It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.

Removing the pre1.9.4 milestone in favor of 1.9.4.
