Fix a crash when several request for the same URL are launched together

* Fix a crash when several request for the same URL are launched concurrently regarding a race condition
* Fix an issue in the `testStopActiveConnection` causing the `URLSession.share` singleton was stuck in the thread and it doesn’t work in another tests
* Refactor the `SwifterTestsHttpRouter` to reuse the `HttpRouter` object
* Add new tests for the threading issue
* Include the new tests added to the `XCTManifests.swift`
* Update the XCTManifests.swift path in the swiftlint config file
* Rename the jobs in CircleCI
* Update the swift-tools-version for the `Package.swift`
