Fix IgnoredReturnValue rule crash in parallel mode (#5724)

* Fix IgnoredReturnValue rule crash in parallel mode

part 2 of #5403:

IgnoredReturnValue crashes due to the usage of a non-thread-safe collection operation.
The usage of `Iterable<T>.plus()` causes this problem.
The crash in parallel mode is fixed by iterating over each collection by itself.

Closes #5403
