Description of problem:
In anaconda, setting up the installation source is not correctly setting method.method, causing the repo setup to fail.

Version-Release number of selected component (if applicable):
pykickstart-1.99.35.1-1.el7 (I think)

How reproducible:
Always

Steps to Reproduce:
1. Start the boot.iso from the 20130820.n.0 nightly
2. Enter the installation source spoke, put in an http url
3. Exit the spoke, spoke now says failed to setup installation source
4. Re-enter spoke, the protocol dropdown has switched back to "closest mirror"


Additional info:
The problem is that the installation source spoke is attempting to set method.method in its kickstart data, but pykickstart is not allowing it.
