migration_diff on none default Datasource uses dump in wrong folder

[maidzen]

I have multiple Datasources.

The migrations are split in a Folders per datasource using the -connection and -source parameter

• config/Migrations (default datasource)
• config/MigrationsLogs (second Datasource "logs" )

....

If i use migration_diff on "logs"

bin/cake bake migration_diff -s MigrationsLogs -c logs

the system looks for the Dump File in "config/Migrations" instead of "config/MigrationsLogs"

atm. we copy the dump file before executing the migration but this can easy lead to errors by human mistake.
