[BUG]: "Limiting the amount of articles in feeds" does not apply when using "Edit child feeds" or "Edit child feeds (recursive)" #2392

Brief description of the issue

For individual feeds it is possible to use the "Limiting the amount of articles in feeds" setting to configure RSS Guard to keep only a set number of the most recent articles for that feed.

When the same setting is configured for a whole folder, using either "Edit child feeds" or "Edit child feeds (recursive)", the setting is not successfully applied to the feeds within that folder or in child folders.

For the debug log, I adjusted the "Limiting the amount of articles in feeds" setting for the "BBC News" feed, then tried to edit the setting for the "bulletins" folder that contains the "BBC News" feed using "Edit child feeds" and then for the "news daily" folder that contains the "bulletins" folder using "Edit child feeds (recursive)". These were both unsuccessful in applying the specified change to the "BBC News" feed.

How to reproduce the bug?

1. Check the current "Limiting the amount of articles in feeds" setting for a given individual feed, by using "Edit selected items", the "Common" tab and then the "Limiting the amount of articles in feeds" tab.
2. Use "Edit child feeds" or "Edit child feeds (recursive)" on a folder that contains that feed to change the "Limiting the amount of articles in feeds" setting (to keep a different number of the most recent articles, for example) and click "ok"
3. Check the "Limiting the amount of articles in feeds" setting for the individual feed again and see that it has not changed to reflect the setting made in step 2.

What was the expected result?

The "Limiting the amount of articles in feeds" setting for individual feeds within a given folder should be adjusted when that setting is changed for the folder containing it using "Edit child feeds" or for a parent of that folder using "Edit child feeds (recursive)".

What actually happened?

The "Limiting the amount of articles in feeds" setting for individual feeds within a given folder does not change when the setting is changed for the folder containing it using "Edit child feeds" or for a parent of that folder using "Edit child feeds (recursive)".
