cover situation when there is no tests in whole execution

[SiarheiDubovik]

Problem details:

1. Particular tags are specified in Cucumber options.
2. There is no Scenarios, which matched these tags
3. Execution starts and goes to com.epam.reportportal.cucumber.ScenarioReporter#afterLaunch where we perform Utils.finishTestItem(RP.get(), rootSuiteId.get());
4. Which means we start "Root User Story" item and immediately try to finish them
5. As result we have error:

Error Message: Test item status is ambiguous. There is no status provided from request and there are no descendants to check statistics for test item id '5b581e9e8a7f71041c4e200c' Error Type: AMBIGUOUS_TEST_ITEM_STATUS

For resolving this I just skip afterLaunch methods if currentFeatureUri value is not initialized (it can be only if no executed scenarios in run)
