change how redirection works after signing in

[DaveDarsa]

@shreddedbacon handling this in server.js if one of the approaches that avoids constant loop between /projects -> /redirectRoute -> keycloak -> /projects...

Unfortunately this doesn't work the way I had hoped. The implementation of this is fine, but the changes to how I hoped keycloak would handle it were not as expected.

We may have to put the redirect value in a cookie and read the cookie back if it exists?
