Untranslated date on admin Activity UI - missing i18n

[danbp]

In french, the date looks like this on the admin activity page

Soumis le 14 May 2015 à 18 h 15 min
Soumis le 5 February 2015 à 3 h 20 min
etc...

To solve the problem, I replaced in bp-activity-admin.php:1531

printf( __( 'Submitted on <a href="%1$s">%2$s at %3$s</a>', 'buddypress' ), bp_activity_get_permalink( $item['id'] ), get_date_from_gmt( $item['date_recorded'], get_option( 'date_format' ) ), get_date_from_gmt( $item['date_recorded'], get_option( 'time_format' ) ) );

by

printf( __( 'Submitted on <a href="%1$s">%2$s at %3$s</a>', 'buddypress' ), bp_activity_get_permalink( $item['id'] ), date_i18n( get_option( 'date_format' ) , strtotime( $item['date_recorded'] ) ), get_date_from_gmt( $item['date_recorded'], get_option( 'time_format' ) ) );

Not sure if it's the best, but at least, it is working.

Digged a bit on Trac before posting and found #5781 - in case of.
