Update website to query f26 atomic
    
    The current code that collects data will blow up if it can't find
    a fedmsg related to a two week atomic release which means the whole
    website can't be built. This has forced us to leave the variables
    at f25 for now.
    
    We'll merge this commit right after F26AH is released on tuesday so
    that the website can get the data it needs from the F26 fedmsg that
    was just sent out.
