Fix publishing of next version

[msujew]

What it does

While the publishing of the next version worked the first time, it didn't the second time (at least not correctly). Lerna attempted to set the version to 1.47.0-next.0, since there was no tag information available in the repo. Since the version was already published, the publishing process did nothing.

How to test

Nothing to test, I'll report back on whether this change worked.
