missing zero-padding in hour display

i guess timestamps display depends on the system date and time settings, but i noticed a difference between riot android and riotx. in riot android, the hour is correctly displayed (like all other dates in other apps and in the system u.i.) as 08:45, but in riotx, the leading 0 is missing. it is displayed as 8:45.

it’s not a big deal, of course, but it seems odd when you are not used to it. i think riotx should display the time in the same way as the system u.i..
