Conditions should check, if Task is enabled, not, if customBuildData fits

[Markus Schulte]

PmdPmdWebItemPlanCondition and PmdPmdWebItemJobCondition are using buildResults.getCustomBuildData() for choosing if to show PMD-pmd-tab.

The should have a look at job's (task-)configuration make this decision.

Maybe "interface Job"::getBuildDefinition[Xml] https://docs.atlassian.com/atlassian-bamboo/latest/ is the right point to start from.

For AbstractTimePeriodCollater, this is even more import - as such builds with and without metric-information will be added to the same value for (for example) one day.
