Unable to add different students to the same time slot

[nus-se-script]

Steps to recreate:

1. add 2 students to the contacts
2. add one of the students to a lesson with lesson add
3. try adding the other student to a lesson with the same fields as before

The app does not allow for adding of multiple students to a lesson which causes it to be unusable for the case that the home tutor conducts group tuition services which is very common in Singapore. This would mean a large portion of the target users would not be able to use the app at all since multiple students can't be tracked for the same lesson which is what is happening.

Recommend to show a warning instead of blocking the user from adding multiple students to the same lesson, this would solve the issue and the user has agency on deciding the next course of action.
