Fix crashmanager testcase storage.

[jschwartzentruber]

We have a Django config setting TEST_STORAGE but within that we store testcases under an additional tests/ folder. This is a trouble point for deployment.

The code is here:

FuzzManager/server/crashmanager/models.py

Lines 49 to 50 in 1826d0b

	storage=FileSystemStorage(location=getattr(settings, "TEST_STORAGE", None)),
	upload_to="tests",

It looks to me like views.py will already do the right thing if this is changed to store files directly in TEST_STORAGE.
