This patch alters the `getRedundantStringBuilderToStringProblem` method with more sophisticated algorithm to detect unnecessary freestanding `StringBuilder#toString` calls. If the call is a part of a polyadic expression it checks if there is at least one string operand (either a constant literal or a local variable or a constant variable or a method call) and based on that information it detects redundant `StringBuilder#toString` calls.
