Solução para erro ao adicionar um label

[RodriguesCosta]

Estou criando essa pull request depois de ver que a pull request #1277 estava vindo da branch errada.

Criei a issue #1276

Ao analisar o código percebi que o problema e que no schema prisma do postgresql não temos um index único usando instanceId, remoteJid porem no schema do mysql ele existe, com isso adicionei esse index.

@@unique([instanceId, remoteJid])

Também aproveitei para adicionar a lista de labels no chat ao chamar o endpoint {{baseUrl}}/chat/findChats/{{instance}}
