findOneOptions does not enforce requiring a where clause

[nyxtom]

Issue description

findOne throws an error if where clauses are not included yet FindOneOptions does not enforce this

Expected Behavior

Due to this change https://github.com/typeorm/typeorm/blob/master/src/entity-manager/EntityManager.ts#L1116-L1120 it would only make sense to have FindOneOptions also enforce the where clause. Otherwise, this part of the code should be reverted.

Actual Behavior

This error is only thrown at runtime, making it difficult to track down when FindOneOptions might be adjusted to be fixed for this.

Steps to reproduce

Create a query using FindOne without a where clause, typescript compiler will not pick this up due to the optional where parameter
