Change Branch UI Not Working

[tecandrew]

Describe the bug

Changing branches using the UI menu, after a fresh pull of a branch, causes an incomplete build. Upon pressing "Install" after "Download" of the branch causes the Comma3 device to get stuck on the Logo upon reboot.

Relevant info when SSH'ing onto the device while stuck on boot logo.

I can also reproduce this by cloning master, switching to master-ci, and then switching back to master fails (the submodule directories are empty).
