undefined method `quoted_scope' for StrongMigrations::WrappedConnection

[ViktorKopychko]

Hi, @ankane

First of all thank you for this really useful gem.

I've encountered an issue when adding a virtual column.
Could you please take a look at the following?

My migration looks like this:
add_column :my_table, :active, :boolean, as: "IF(finished_at IS NULL, 1, NULL)", stored: false

When I run it the following error is printed in schema.rb

Could not dump table "my_table" because of following NoMethodError
undefined method `quoted_scope' for #<StrongMigrations::WrappedConnection:

I've discovered that this method is called from mysql/schema_dumper via send

scope = @connection.send(:quoted_scope, table_name)

StrongMigrations::WrappedConnection uses delegate_missing_to :@connection which does not cover private methods so I was able to fix it by adding

def quoted_scope(name = nil, type: nil)
   @connection.send(:quoted_scope, name, type: type)
end

to it.

What do you think about this? Should I make a PR?

Thanks!
