Fix python fuzzing strategy

[tamarinvs19]

Description

Version from #1893 has the following problem: when we get result from cache we don't save this execution in limitManager so fuzzer use all time with one annotation instead of using next annotations from type inference algorithm.

Fixes bug from #1874

How to test

Manual tests

1. Try generate tests for some python function without full annotation, e.g.

def f(x: list):
    return len(x)

2. Expected: tests had been generated

Self-check list

Check off the item if the statement is true. Hint: [x] is a marked item.

Please do not delete the list or its items.
