PoStreamReader::readLine() throws an error on module install

Problem/Motivation

I've downaloaded a new module and want to enable it, but get fatal error. I've tried to enable several different modules and every time get this error:

$ drush en honeypot 
>  [notice] Checked fr translation for honeypot.
>  [notice] Checked nl translation for honeypot.

Steps to reproduce

1. You should have a multilingual site.
2. Add a new module, e.g: composer install drupal/honeypot.
3. Enable it: drush en honeypot.

Expected result: module is successfully enabled, no errors.

Actual result: module is enabled, but there was a php error on translations import during module install.

Proposed resolution

After some investigation it turned out that we can modify just 1 line in PoStreamReader::readLine() to fix the issue, see a patch below.
