Fix homeserver verification with wildcards certificates.

Disable v2 by default.
Add migration to fix the accepted table (due to sqlite unable to change constraint, drop table and create again).
Fix displaying the expiration period of the new token.
Remove duplicated code.
Use v1 single lookup when receive the request with `none` algorithm and the only one argument.
Hide v2 endpoint if v2 API disabled.
