Does not work with Rails 5.1

Not sure why, but doesn't work with Rails 5.1.

ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR:  relation "my_table" does not exist ... )

I tries to use PG but it should be mysql.

I'm seeing this as well. Even doing a .connect query on the SecondBase::Base class runs on the first db and not the second. Rollback to Rails 5.0.2 works fine again.

I'll find some time to play with this soon. One thing I noticed today. First PR never made it into Rails core:

• new database.yml format rails/rails#27611
• Allow 3-level DB configs to group connections by environment rails/rails#28095

Published v2.1.4 with Rails v5.1 fixes. Thanks!
