    e_get_account_by_uid(): Also handle CamelTransport UIDs.
    
    Enhance e_get_account_by_uid() to also accept CamelTransport UIDs.
    
    The convention we use to distinguish them is simple:
    
       Given an EAccount UID:
    
       - The CamelStore UID is the EAccount UID verbatim.
    
       - The CamelTransport UID is the EAccount UID + "-transport".
    
    So just check for a "-transport" suffix and truncate it.
