[CAL-3098] before/after buffer not working correctly for events with seats

[CarinaWolli]

Issue Summary

Before and after event buffers don't work correctly on events with seats.

Steps to Reproduce

1. Create an event type with seats and 60 mins before + 60 mins after buffer
2. Book first seat of a slot
3. After the first seat is booked the buffers should already be applied, but slots are still open before and after 60 minutes of the event

It's only not working for the event type itself. For all other event types (with or without seats) the buffer for this seated booking we just made is correctly applied and these slots are not shown as available.

hey @keithwillcode I have just found what is issue here but I don't know what exact solution will work here if the event is booked by one user that means he should not able to see slot open for any event type and all other users will able to book the event type if that's the case I have solved issue

Let's say the seated event has a before buffer of 2 hours. If the first seat gets booked, then the buffer should be applied. Meaning: the slots 2 hours before the booking are not available, the slot from the booking itself is still open for the rest of the seats, and the slots 2 hours after are blocked too (as the next slot also need the 2 hours before buffer)

@Rahul190299 does this make sense?

i have checked in code the booked slot is not get added to busy slot array due to and condition applied on event type hence its not working for event type itself for rest all event type in my fix i have added check for user who booked slot instead on event type and its working fine but i doubt it will not break other things
