Restore interactive-serialization-basic test

[#62048198]
Make sure that interactive controller copies template definition

[#62048198]

So the serialized version of template is equal to initial template
provided by author.
Fix issue in select box view that prevented option from being selected

[#62048198]
Update grapher mock that is used in tests

[#62048198]
Slightly change some interactives to avoid serialization test fail

[#62048198]

Of course it's an interim solution.
The problem is more general - if onLoad or parameter's onChange script
changes parameters, what should we do about it?

Is it expected that interactive serialization includes these changes?
I guess so, however it makes automated testing a bit difficult.

In this commit I've just changed parameters values to match computed
values set by onChange scripts.
