JsoupSiteParserTest: fix a sporadic test failure.

isFullyInitializedWhenAllMandatoryFieldsAreSet test could fail sometimes
with the following error:

  JsoupSiteParserTest.isFullyInitializedWhenAllMandatoryFieldsAreSet:286 JsoupSiteParser[name=wTtSagJviB, matchedUrl=http://example.com/page/H1//h//6z, categoryLocator=null, countryLocator=null, shortDescriptionLocator=null, imageUrlLocator=null, imageUrlAttribute=src, issueDateLocator=null, sellerLocator=null, priceLocator=null, currencyValue=null] expected to be fully initialized
Expected: is <true>
     but: was <false>

Correction for 96b173b commit (#685).
