Timesheet=> The sum of all hours of one project in one day more than 24.00 hours

[JaneKamneva]

Chrome v. 58.0.3029.110 (64-bit), Opera v. 45.0, FF v. 53.0.2 (64-bit);
OS: Linux Ubuntu 14.04

Steps:

1. Click "Timesheet" tab
2. Choose any date and press several times "+" button in order to add more projects for this day
3. Enter hours which sum more then 24

Actuall result: the application allows to do it. It is a logic mistake.
Expected result: the sum of all working hours of one day cannot be more than 24.
