Default translator does not work if network blink while token fetching

Original problem: https://github.com/translate-tools/core/issues/130 The problem is now fixed, we should update package with translators and issue new patch version Steps to reproduce - Select Microsoft translator - Reopen browser - Disable network - Click linguist popup, try to translate any text - After error, enable network back - Try translate again Expected behaviour is we have network error first, and then translation works fine after network on. Currently we locked on network error even when network is available.
