22970	Migration dependencies not correctly calculated	Jeroen Dekkers	Andrew Godwin	"When working with the new migrations I hit a bug that dependencies between migrations aren't correctly calculated. Migrations that add a ForeignKey to a model in another app that was created in the second or later migrations of that other app have a depenency on the first migration instead of the later migration. Steps to reproduce:

* Start a new project and create two apps myapp1 and myapp2
* Add a model named Model1 to myapp1
* Run makemigrations, resulting in 0001_initial.py that creates Model1
* Add a model named Model2 to myapp1
* Run makemigrations, resulting in 0002_model2.py that creates Model2
* Add a model named Model3 with a !ForeignKey to 'myapp1.Model2' to myapp2
* Run makemigrations, resulting in 0001_initial.py that creates Model3

The 0001_initial.py of myapp2 will then have `('myapp1', '__first__')` as dependency while Model2 is created in the second migration.
