[FIX] devtools: Fix race conditions in tree lodaing

This commit fixes some race conditions that were happening due to the
loading of the tree being sometimes triggered at the same moment as the
DOM patch. This would result in some destroyed component still being
present in the devtools' tree. This commit also ensures that the loading
of the tree is synchronous in regard to the component details loading.
