Title: Always reenable _dump task in AR databases rake. Closes #5030

This allows the internal :_dump task to be called as many times as required.
For instance, `rake db:migrate:redo` calls two tasks that internally call
:_dump, and without reenabling it to be reinvoked, the database was left in
incorrect state.

This should be applied to 3-2-stable as well.
