[QA] status code check in SpacesContext theUserCreatesASpaceWithQuotaUsingTheGraphApi

[phil-davis]

Describe the bug

The code does an exact equal === check:

		if ($response->getStatusCode() === '201') {
			$this->addCreatedSpace($user, $response);
		}

Investigate what is really happening, and what the consequences are for the test scenarios and scenario cleanup.
Make the appropriate fixes to the test code.

But getStatusCode() returns an int, so this check will never be true.

Expected behavior

addCreatedSpace happens when a new space is created by the tests.

Actual behavior

addCreatedSpace does not happen.

Setup

CI
