util: Rename function to calls_find_in_model() and adjust documentation

Since it works for GListModel rename it appropriately.

It used to provide an inline implementation for g_list_store_find()
behind a glib version guard, but we bumped minimum version in
cfd3c2a7fe
so the docstring was updated and made more succinct.
