auth: wait for auto-discovery before showing view

This partially reverts change from
b194ad205b558803b7a1c0c8cc177e5b14e80835 which introduces loading of
dashboard while auto-discovery takes place in background. The cons is
that user will feel that login is taking time, but he'll be allowed to
redirect to a page before session timeout/logout. In #456 a similar
usability issue was added. However, a tab refresh will be faster
because in b194ad205b558803b7a1c0c8cc177e5b14e80835 we've added support
for using cached discovered APIs.

Fixes #456
