confusing-magic-project-creation-when-missing

Snippet from IRC:

11:46 jimbaker: thomasem, yeah, that's not good
11:47 thomasem: With that, what's the reason to bypassing and going with raw SQL?
11:47 jimbaker: automagically creating projects is just a little too special for these snowflakes
11:47 jimbaker: thomasem, purely historical
11:47 jimbaker: that usage needs to die
11:47 thomasem: Okay. I'll open a bug.

Essentially, we're wanting to remove this magic and move more towards a bootstrap user setting up the projects separately as the first step before a region, cell, etc. is added.

Acceptance Criteria:
* Function "find_or_create_project" is removed from validations.py along with references to it.
* Any bootstrapping for testing or existing deployment is shored up to maintain status quo.
