by_pk causes stack overflow when used with single primary key while table define composite primary key

[hieuk09]

Describe the bug

When using by_pk with one value while the table has composite primary key, ROM can raise stack overflow error.

To Reproduce

• Create a table in DB:

create table users (
  id VARCHAR(50),
  tenant_id VARCHAR(50),
  primary key (id, tenant_id)
)

• Run the below snippet

require "rom"

rom = ROM.container(:sql, 'postgres://localhost/test') do |config|
  config.relation(:users) do
    schema(infer: true)
    auto_struct true
  end
end

users = rom.relations[:users]
users.by_pk('0049d2d1-b433-48d7-818a-a2672ae05fa').one

Expected behavior

The error should be raised with incorrect number of argument message.
