Description

A user was reporting that their PDF file uploads were being assigned the
mimetype of "text/text/application/pdf", which is completely bogus. If
splitting on '/' produces anything other than a list of two strings, don't
allow it to proceed.

Testing Done

Ran unit tests.

Can we add a comment above this conditional talking about this, and referencing the bug? It's obscure enough that I think it's worth calling out.

(I'm still a bit skeptical that browsers would be sending such a broken mimetype, but it doesn't hurt to have this I suppose.)
