create_continuous_aggregate not reversible from AR migration

[intermittentnrg]

I tried to run rake db:migrate:down VERSION=xxx on a AR migration that used create_continuous_aggregate and it just tried to run create_continuous_aggregate again instead of dropping it.

It should either work, or it should raise irreversible migration error.

Further drop_continuous_aggregate did not exist, but drop_continuous_aggregate does exist.
Turns out alias_method entry is missing for drop_continuous_aggregate.

alias_method :create_continuous_aggregates, :create_continuous_aggregate
