MariaDB: Sqitch doesn't respect registry config anymore

[tiberiusferreira]

Hello, previous to #854 sqitch used to respect the registry and use that value as the sqitch schema.

That doesn't seem to be the case anymore. Maybe that was a MySQL specific behavior? If so, could it be replicated for MariaDB?

Example of error:

# On database TestMariaDB
Table 'TestSchema.changes' doesn't exist

With config:

[core]
	engine = mariadb
	registry = sqitch

[theory]

Does it work if the schema exists? Might be that it's not looking in the right place simply because the schema didn't exist when it connected.

Oh, I think I know what the issue is. On line 65 of lib/App/Sqitch/Engine/mysql.pm, try changing ->uri to ->registry_uri:
