plugin ignores custom definitions when places in an external file

[tomeraz]

My serverless.yml references an external file:

custom: ${file(../../serverless.common.yml):custom}

Placing settings inside serverless.common.yml:

custom:
  dotenv:
    path: ../../.env

serverless.dotenv-plugin ignores these settings.
When debugging plugin code, row 13 leaves this.config undefined:

    this.config =
      this.serverless.service.custom && this.serverless.service.custom['dotenv']

because this.serverless.service.custom equals: "${file(../../serverless.common.yml):custom}"

This looks like a duplicate of #52, and I would like to keep the conversation. Please reopen this issue if it is not.

Thanks!
