Avoid NPE for databaseStorageModule

Exception java.lang.NullPointerException:
  at com.nextcloud.talk.conversationinfo.ConversationInfoActivity.handleConversation (ConversationInfoActivity.kt:686)

Handle conversation is called when capabilities are retrieved, which can occur before databaseStorageModule is created. The fix was to call initObservers after the module was created.
