Release 5.0.0 no longer stable on fresh installation

[collinkatz]

Using a fresh installation of release 5.0.0 I encountered two issues.

1. I ran into a 500 Internal Server Error after the initial build and trying to access the login page. This is the same issue as is detailed in Server responding with 500 Internal Server Error in fresh installed. This issue is resolved for the master branch and was fixed in this pull request, and applying the change from that commit resolved this particular issue for me.

2. When trying to login using the supplied credentials in conf/local.yml, I would recieve an error TypeError:n.response is undefined which would appear under the login button. After checking the POST request data, it appeared no data was being sent, and I believe this is the same issue detailed in this discussion. Applying the fix detailed by elegantmoose, i.e. switching the magma plugin's branch to master, resolved this issue for me although the sidebar displays version "4.2.0".

I suggest applying these changes retroactively to release 5.0.0 or making a new minor release soon as these issues render the current release unstable without this fix.
