[Android] Playlists: fix media not set over ML_SIZE_LIMIT

vlc-android | branch: master | Duncan McNamara <dcn.mcnamara at gmail.com> | Fri Aug  5 11:16:58 2022 +0200| [c6ae7d32f2f9a09cfc41e2ff61dcf162263afa46] | committer: Nicolas Pomepuy

Playlists: fix media not set over ML_SIZE_LIMIT

With pagedLists when a list is over the MEDIALIBRARY_SIZE_LIMIT,
media over it won't be set, causing crashes. This forces each media to
be set when the mediawrapper list is over the constant.

Fixes #2623
