v1.7 breaks LEFT JOIN on Postgres

[CydeSwype]

Describe the bug Left join doesn't work. Note the ON ."network_merchant_id" below in the broken SQL output.

Information

• Version of Medoo: 1.7
• Type of Database (MySQL, MSSQL, SQLite...): Postgres
• System (Liunx\Windows\Mac): Linux and Mac

Detail Code This PHP code:

$result = $db->select("table_name", [
    "[>]network_merchant" => ["network_merchant_id" => "id"],
], [
    "table_name.id",
    "table_name.network_id",
], [
    "ORDER" => ["table_name.id" => "ASC"]
]);

Actual output produces the following broken output (from 1.7):

SELECT 
    "table_name"."id",
    "table_name"."network_id",
    "table_name"."network_merchant_id",
FROM "table_name" LEFT JOIN "network_merchant" ON ."network_merchant_id" = "network_merchant"."id" 
ORDER BY "table_name"."id" ASC

Expected output but used to produce this correct output (from v1.6.1):

SELECT 
    "table_name"."id",
    "table_name"."network_id",
    "table_name"."network_merchant_id",
FROM "table_name" LEFT JOIN "network_merchant" ON "table_name"."network_merchant_id" = "network_merchant"."id" 
ORDER BY "table_name"."id" ASC
