feat: Delay clients synchronize() call 10s after startup

Call to `synchronize()` may slow down the startup process but is not
necessary for the app to work

It is here only to update the cozy-settings's OAuth clients list to
display the last connexion to the app

So we chose to delay this call a short delay after the startup (for now
10s)

By doing so, we may fail calling the `synchronize()` method if the user
closes the app less than 10s after opening it, but as this is used only
for display purpose, we chose to consider this as not-critical
