loadNamespaces() doesn't keep resolving order when the second request completes before the first one

[yeromen]

🐛 Bug Report

If we make several requests with loadNamespaces() to different namespaces, in case when the second completes faster than the first one, the first promise resolves first when it's not loaded in fact yet. The bug appeared with version 21.8.0 and higher.

Case 1: The first request completes first - everything is OK

Case 2: The second request completes first - Bug

To Reproduce

Sample: https://codesandbox.io/s/optimistic-tdd-sycrtt?file=/src/app/app.component.ts

Expected behavior

loadNamespaces() resolves when the appropriate namespace loaded, for example as it worked with version 21.7.1

Can you create a test that reproduces your behaviour like this, please: https://github.com/i18next/i18next/blob/master/test/i18next.backend.concurrentLoad.spec.js

@huntharo maybe have a look at it? Was introduced probably because of your PR: #1768

[adrai]

v21.8.8 should fix that

[adrai]

have you tried v21.8.8 ?

Works as expected with v21.8.8, thank you!
