#2736 Repetition on weekdays only not working as spected

[L Diaz]

It seems that repetitions every n days created with the flag 'weekdays only' still take into account the week-end days for calculations.

So, an event created this 1 of June, to be repeated every 9 days on weekdays only, is repeated on days 10 and 28, but should be on days 14 and 27.
