NPE when trying task createGranularIssuesDataSets because of blank description field

[Prokhorovmax]

Task crashes with following error:

Exception in thread "main" java.lang.NullPointerException
	at com.koval.resolver.common.api.util.TextUtil.simplify(TextUtil.java:17)
	at com.koval.resolver.processor.issues.granular.core.GranularIssuesDataSetsCreator.create(GranularIssuesDataSetsCreator.java:65)

> Task :createGranularIssuesDataSets FAILED

Happens when field description of an issue is empty.
