show password manager message box on all origins

fix brave#2957
note that this partially un-fixes brave#1928.

Auditors: @alexwykoff

Test Plan:
1. go to developer.apple.com
2. click on 'Account' in the top right
3. enter your apple username and password
4. the login page should redirect to https://developer.apple.com/
5. after the redirect, you should still see a password manager dialog from Brave that says 'Would you like Brave to remember the password for [username] on https://idmsa.apple.com?'
