Reset the password is marked as failed… but I've received the email

[g123k]

Hi everyone,

I've just tried the feature in the app, by passing my username.
I have an error stating that "my username and/or password???" is incorrect.
… but I've received the email!

So, basically two issues here:

• The error message is incorrect (we shouldn't talk about an invalid password)
• The error shouldn't be visible… if it's actually a success

This is an error on the Dart package: openfoodfacts/openfoodfacts-dart#774

I will create a PR, as it's normally fixed on our side.
However, the server doesn't respond with the text expected.

An issue is opened: openfoodfacts/openfoodfacts-server#8819
