Still can create schedule reservation on the resource in the past time

[William-Le88]

Schedule shouldn't be allowed to created in the past time.

When I tried to test creating the schedule in the past time ( for example now is 2:30pm on 23rd Feb 2021), the past time schedule created was from 9:30am to 12:00pm, and the schedule still be allowed to create.

We should not allow users to create the reservation schedule in the past time and only allow users to create the reservation schedule in the future time.
