Is your feature request related to a problem? Please describe.
If a single item on a list causes an exception, whether that be for it not being found, or not getting proper response from Lidarr API, it will cancel the whole list import. This is very frustrating when you have large lists that fail for one item.

Describe the solution you'd like
Add exception handling that will log the failure and move to the next list item without cancelling the entire list import task.

Describe alternatives you've considered
There are not really any alternatives for this, I usually just split my list up into smaller batches to try and find the culprit, since the trace logs only show the artist ID, it's difficult to resolve that to an actual artist. This is very tedious and time consuming.
