Trying to "search" issues with fixVersion fails due to Missing argument 1 for JiraRestApi\Issue\Version::__construct()

[alexa-rbo]

Here's the error message (slightly truncated):
Missing argument 1 for JiraRestApi\Issue\Version::__construct(), called in /home/alexa/PhpstormProjects/release/vendor/netresearch/jsonmapper/src/JsonMapper.php on line 544 and defined

And here's stack trace:

I'll submit PR shortly.
