Force Nameprepping of JID domain parts
The IDN.toAscii()/IDN.toUnicode() family only namepreps the original domain passed to it if it contained non-ASCII characters. This means that for all-ASCII domains, no canonicalization is performed, which leads to issues like case-sensitivity. This workaround explicitly namepreps domain parts before calling IDN.toAscii() on them, in order to get a canonicalized representation (most notably, case invariance). A basic DB migration is also included.
