assertEquals() does not compare the type. It can not only be a float,
it can even be a string. E.g. 9 and '9' are considered equal.
Worst case scenarios are:
* 0 is considered equal to any "falsy" value, including the empty
string.
* 1 is considered equal to true.
assertSame() does not have any of these confusing edge-cases.

As noted in Ic22075bb5e, UserNotificationGatewayTest relies on the presence of
globals. When Ic22075bb5e is merged, UserNotificationGatewayTest will fail in
CI. This patch injects the configuration object into UserNotificationGateway.
