Use 302 (Temporary) Redirect instead of 301 (Permanent)

[nelsonic]

At present we have a 301 status code when auth gets redirected:

auth_plug/lib/auth_plug.ex

Line 141 in cf6e2eb

status = 301

We actually want a 302 so the browser does not think the auth page is the new /profile page. 💭

This is a quick/easy fix.

• Update lib/auth_plug.ex#L141 to 302
• Update all tests that assert 301 to 302
