feat(core): Run all mutations within transactions

Relates to #242

BREAKING CHANGE: The TypeORM `Connection` should no longer be directly used. Instead, inject the new `TransactionalConnection` class, which wraps the TypeORM connection and enables database transactions to be used in conjunction with the new `@Transaction` decorator.

The `getEntityOrThrow()` and `findOneInChannel()` helper functions have been deprecated and replaced by methods with the same name (but slightly different signature) on the TransactionalConnection class.
