[Report] Dependency tree does not shown dependsOnGroup methods

[martingrossmann]

Describe the bug
The dependecy tree in method details shows dependened test and setup methods. The dependency of test methods can done with TestNG attributes dependsOnMethod and dependsOnGroup.
In case of dependsOnGroup the methods are missing in the tree.

To Reproduce
Two test methods are linked via dependsOnGroup

@Test(groups = "myGroup")
public void test01() {
}

@Test(dependsOnGroups = "myGroup")
public void test02() {
}

In report the dependency tree of test02 does not contain the method test01.

Environment(please complete the following information):

• Testerra 1.3

Not really. This bug describes the visualization in the report. Here I asume the TestNG config is fine but Testerra cannot show all dependencies.
