This PR fixes the issue with variable resolution during predicates interpretation as initially reported by @amimart.
Example:
trueBasically, the assertion functions (used to implement predicates) no longer verify the groundness of terms. They now only resolve terms that are essential for the assertion. For example, to confirm that a term is a pair, only the compound term is resolved, without resolving the arguments of the compound.
New test cases have been introduced to improve coverage.
