* Fix sync client ignoring directories
Current implementation of the sync client does not properly send requests to a
self-hosted sync server if the URL has directories.
If the self-hosted sync URL is `https://example.org/foo/bar/`, Anki is expected
to send requests to `https://example.org/foo/bar/sync/hostKey`. Instead, it will
discard the directories and wrongly send requests to
`https://example.org/sync/hostKey`.
Fixes: e5d5d1d ("Fix panic with invalid sync server URL with port")
