[calls] record-row: Only create popover when needed

[Evangelos Ribeiro Tzaras <devrtz src gnome org>]

commit 4df3ea005dac748d42ff7aa84d30a78afd89a281

    record-row: Only create popover when needed
    
    Creating a popover for each CallsCallRecordRow comes with a big performance
    hit when scrolling the history, so we should avoid doing this.
    
    Fixes #198
