Fix the access to child services from parents under My Services

[skateman]

When I hid the services in #5335 we didn't count with the fact that services might be nested into each other. Unfortunately, the child service access is only doable through the tree_select route and it has been accessed by miqTreeActivateNode. Without the node actually being in the tree, this function did nothing and so the child services weren't accessible.

I'm proposing a workaround to call the tree_select directly from the miqTreeSelect function. This is not a permanent solution, these areas where we access items exclusively through tree_select should be refactored.

Navigating back to the parent service in hammer can be done using the toolbar's back button, in upstream we should also update the breadcrumb generation logic to contain the hierarchy.
