- This releases' "autogenerate index detection" bug, when a MySQL table
includes an Index with the same name as a column, autogenerate reported
it as an "add" even though its not; this is because we ignore reflected
indexes of this nature due to MySQL creating them implicitly. Indexes
that are named the same as a column are now ignored on
MySQL if we see that the backend is reporting that it already exists;
this indicates that we can still detect additions of these indexes
but not drops, as we cannot distinguish a backend index same-named
as the column as one that is user generated or mysql-generated.
fixes #202
