action-listener-middleware memory-leak test

Test memory leaks using memory profiler available at chrome-devtools>memory.
Use the profiler in incognito mode.
You can test it inside code-sandbox but it is strongly suggested that you use compiled version (see `./dist` folder) because code-sandbox periodically refreshes the page.
The `heavy-string` is either in `(concatenated-string)` or in `(string)` section and starts with `heavy-string-`.


This test shows the impact of long running listeners.
