fix: show all provider models when no providers connected

When no providers were connected, the model dialog would hide models
that were in the recent list, but the recent section wasn't being
displayed. This caused models to completely disappear.

The filter was checking recentList (which only contained non-favorite
recent items) instead of recents (all recent items), causing models
to be incorrectly filtered out of the main provider list when the
recent section wasn't shown.
