Create a transaction whenever a user settles up

[IsaacCheng9]

Specification

• Currently, there is no transaction displayed when a user settles up.
  • This makes it confusing, as it can seem like the expenses don't add up.
• To fix this, create a transaction alongside the list of expenses in the left panel.
  • For example, in the scenario below, user1 settled up £7.50, so it should have a fourth row on the left panel to reflect this.

Should we store settlements in the expenses collection in mongo ? We need persistent storage for settlements in order to list them with expenses.

I think it would be best to create a new collection for settlements so we have some separation, but if that complicates things heavily on the front-end then we could implement settlements as negative expenses?

It may be easier to start with negative expenses for now, if we had a separate collection for settlements the frontend would have to sort settlements and expenses together by date and time on every refresh unless we also had a transactions collection which stored both.

Let's go with this then, and rename the collection to transactions to represent this.
