fix(ui): bring back non-empty check to ThemeName (#13175)

Followup to https://codeberg.org/forgejo/forgejo/pulls/13110, which introduced a regression.

`SignedUser` is not guaranteed to be nil for guest users. Instead, we're setting it to non-nil user with ID 0 in some places, like:
e7c45cd9c8/services/context/org.go (L168-L171)

In https://codeberg.org/forgejo/forgejo/pulls/13110, I removed the check assuming it was for handling cases where real user's theme is set to "", after making sure it can't happen. This broke display of org pages to guest users and no tests caught it.

This unreliability of `SignedUser` doesn't seem ideal but I've assessed my chances of improving this without introducing more regressions as low, so I just brought the check back.

Noticed on v16.next. Demonstration:
