Force the app to start updating the account information just after it is imported/created.

This wasn't happening automatically the first time the account was imported, the the user had to close and reopen the app for the transfers update to take place. The problem was that the account information was only fetched from the shared preferences when the app started, thus a method to force the fetch was introduced just after the user imports/creates his user account.
