Fix inconsistencies with UserId (#906)

Browse Source 
* Fix inconsistencies with UserId

The account user id isn't an UUID. This PR adds a new UserId type with
the correct value ordering to avoid mismatch with LibHac's Uid. This also fix
an hardcoded value of the UserId.

As the userid has been invalid for quite some time (and to avoid forcing
users to their recreate saves), the userid has been changed to "00000000000000010000000000000000".

Also implement a stub for IApplicationFunctions::GetSaveDataSize. (see
the sources for the reason)

Fix #626
