#16772 partial fix backoffice redirect after login

[kows]

With the mindset of better anything than nothing: partial fix for #16772
Seems to enable login screen for local (hash needed) and OpenId login (reason for encoding).
This does not fix the flow when AutoRedirectLoginToExternalProvider is enabled since I have no idea yet how I would get the anchor value serverside or work around that issue.

Thanks for this @kows - I've verified that it works for local login and also when I've registered and external login provider (Google). Will merge in and include in 13.10.

I'm not sure this is working, or at least it's creating an odd side effect for us:

• Log into the CMS and open a content page, e.g https://domain/umbraco#/content/content/edit/58270
• Delete cookies from application tab to simulate logout, or let CMS timeout naturally
• If CMS page remains 'logged in', navigate to a different CMS page, e.g https://domain/umbraco#/content/content/edit/58271
• Log back into the CMS
• The site ends up redirecting to https://domain/#/content/content/edit/58271 (no umbraco in the url, effectively loading the FE website)

I'm not seeing the issue if I drop the version back to 13.9.3

@AndyButland we are seeing the same issue as mentioned above by @AdTarling

Should be resolved for 13.11 - see #19984 (linked above).
