Disable not used queues/database modules on E2E tests

[hectorgomezv]

Summary

This PR aims to fix the following CI error while running E2E tests:

  ● Test suite failed to run

    Unhandled error. (Error: Channel ended, no reply will be forthcoming

      at rej (node_modules/amqplib/lib/channel.js:181:9)
      at ConfirmChannel._rejectPending (node_modules/amqplib/lib/channel.js:184:7)
      at ConfirmChannel.toClosed (node_modules/amqplib/lib/channel.js:150:10)
     ...

While the root cause is not fully clear, chances are a race condition between the tests causes the shutdown hook to try to close an amqp channel that is already closed. This PR does two related things:

• It wraps the QueuesApiShutdownHook.onModuleDestroy code into a try-catch block, so the possible error is handled (and therefore it shouldn't cause a test execution failure),
• It disables the infrastructure that is not involved in the E2E tests (by overriding PostgresDatabaseModule and QueuesApiModule).

Changes

• Add a try-catch block to QueuesApiShutdownHook.onModuleDestroy so possible errors are handled.
• Disable PostgresDatabaseModule and QueuesApiModule where they are not required.
