When Python methods is called from MuranoPL code its result was not
converted to immutable value that yaql 1.0 operates on.
For example consider that we have
def foo():
return [1]
and MuranoPL code:
- $val: list(1)
- $cmp: foo() = $val
as a result $cmp was set to false because [1] != (1,)
This bug caused all Docker/Kubernetes apps to break on re-deployment
