Duplication of logs when an ES error occurs

[mashkovtsev]

Hi,
we are faced with the problem of duplicating non-erroneous logs, when erroneous logs occur.

Reproduced on:

• Node.js 12.*
• elastic search: 7.*
• winston-elasticsearch: 0.16.1

I have prepared a demo: https://github.com/mashkovtsev/demo-bug-winston-elasticsearch.

Thanks!

You can set retryLimit: -1 in temporary before this bug fixed.
