Don't attempt to initialize manga details from BrowseSource or Search screens

This was effectively DDoSing sources as it does a request for every entry to get the details (primarily a cover image).
The expectation now is that users have to open individual entries to load the details/cover if needed.
This isn't necessary for most sources, which are able to provide covers as part of the listing normally.
