loaderUtils.parseQuery() is deprecated

[eXaminator]

We started using this loader a few days back and now receive a deprecation warning every time we run our tests. Here is the full waring plus the matching stacktrace:

(node:1873) DeprecationWarning: loaderUtils.parseQuery() received a non-string value which can be problematic, see https://github.com/webpack/loader-utils/issues/56
parseQuery() will be replaced with getOptions() in the next major version of loader-utils.
