Silent ignore media import errors

[kevinvugts]

Is your feature request related to a problem? Please describe.
When importing collection types from A to B sometimes it happens that media files like images/video's can't be parsed. Currently this is causing the actual entities itself not being imported at all.

Describe the solution you'd like
It would be nice if no matter which media file failed, the important just silently continues it's import. And like it already does now, it should just return the data.failures back to the user.

Please let me know if you want to discuss this any further!
