Title: Keep JavaBasePlugin ability to run a single test.

In normal 'java' project you can pass a runtime parameters to run a single test e.g.
`testPaidNormalDebug -DtestPaidNormalDebug.single=AdditionOperationTest`

To respect this we can override the include pattern only if that property is not set.
