FIXES CORE-1861
### What
Add workflow for refreshing a payment collection.
The idea is that on all cart updates, we want two things to happen (in the context of payments) 1. the currently active payment sessions should be destroyed, and 2. the payment collection should be updated with the new cart total.
We do this to ensure that we always collect the correct payment amount.
From a customer perspective, this would mean that every time something on the cart is updated, the customer would need to enter their payment details anew.
To me, this is a good tradeoff to avoid inconsistencies with payment collection.
Additionally, I updated the Payment Module interface with `upsert` and `updated` following our established convention.
### Note
This PR depends on a fix to the `remoteJoiner` that @carlos-r-l-rodrigues is working on.
Update: Fix merged in #6602

Currently, if the v2 flag is not enabled it can lead to issues if the modules are part of the medusa config as they will get loaded anyway leading to issues if the migrations did not ran
new wrapper for medusa integration tests.
for now it is only applied to the modules directory, but it could be used in the api integration tests or any other integrations that requires a db and a server up and running.
It is not perfect, but I wanted to have something working and centralised before improving it, also avoiding too many conflicts with other prs
