Subject: [PATCH] [api] Convert tables created without default charset to utf8.
Some tables were created without default charset explicitly specified.
This causes these table to get theif default charset from database default,
that in turn got its default charset from MySQL/MariaDB server default.
However, tests assume that default charset is utf8, but MySQL/MariaDB server
uses some distribution default that my be something different.
Hence, it would be better to not rely on MySQL/MariaDB server
using utf8 as default and specify charset explicitly.
This change adds a migration that explicitly sets database charset to utf8
and converts tables that were created without default charset to utf8.
