Date should show in correct locale format

Was speaking to a contact who has macOS and he didn't like how the date was showing in US format. He would like the date to show in accordance with the date sets in the system locale settings which is dd/mm/yy. Unsure of exactly where this date was showing incorrectly as we do not have a macOS. @kkostiuk are you able to find where this is? If so does another issue need to be created in the Jami macOS client section?

The date format is also incorrectly shown in the Jami GNOME client. The chatview seems to show the date correctly according to the system locale setting. Please see image below. @sblin can you please fix the date format to show from mm/dd/yy to dd/mm/yyyy?

If the last conversation was in the last week, can the date in the conversations panel be replaced by the day? i.e. Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday

If the last conversation was in the last day, can the date in the conversations panel be replaced by the time in accordance with the system time setting? i.e. 6:57 PM, 6:57 p.m. or 18:57

Do the other clients need fixing too? Or is this a issue with the daemon or otherwise?

Thank you
