Honour JID part length in ICUConverter
ICUConverter allowed jidparts greater than 1023 bytes during
stringprep.
The SConscript of StorageTest did not work when libidn had been
disabled, which prevented test=unit from completing.
Test-Information:
Unit tests pass on Debian 9 in a build with ICU and ASan enabled.
