AccountObserver listeners were being triggered correctly, however, during every time
we open HomeFragment, home menu gets re-created, which causes us to re-run the initialization
block. Before this patch, the init block would never touch the account manager.
After this patch, it will query it if account manager has already been initialized.
`init` blocks are executed before `val` initialization which is declared afterwards
in the class. In this case, we had `quitItem` and `reconnectToSyncItem` as lazy,
but declared after the `init` block which may need them. And so, while this compiles
just fine, in practice we run into an NPE as the `init` block tries to get the lazy's value.
Simply re-ordering initialization fixes the problem.
This refactor "reverses" relationship between these two classes, allowing
HomeMenu to inform its parent, HomeFragment, of any changes to the menu.
Once that's in place, we start observing account manager changes (once its ready)
for account problems.
This solves two problems:
- initialization of the account manager is no longer necessary to build a home menu
- home menu now starts observing changes to the account manager's state (before it was static)
