Misleading documentation of apps.ready condition

[Petr Dlouhý]

From the discussion on ​django fieldsignals page it is clear, that the ​documentation about AppConfig.ready() and apps.ready variable could be quite misleading.

On ​https://docs.djangoproject.com/en/1.9/ref/applications/#django.apps.apps.ready in section about apps.ready is written:

Boolean attribute that is set to True when the registry is fully populated.

And in the section about AppConfig.ready():

It is called as soon as the registry is fully populated.

Which might lead to conclusion, that apps.ready variable is True in AppConfig.ready(), which is not true (as could be seen in ​Django code).

Is this better?

Boolean attribute that is set to ``True`` after the registry is fully
populated and all :meth:`AppConfig.ready` methods are called.

[Aymeric Augustin]

Yes.
