Allow connection object to take unamed client by default

[gabrielstuff]

Instead of:

"connection": [
        "spacebro-client/users::find => score-api/users::find",
        "score-api/users updated => spacebro-client/users updated",
        "spacebro-client/score::find => score-api/score::find",
        "spacebro-client/match::find => score-api/match::find"
]

write:

"connection": [
        "/users::find => score-api/users::find",
        "score-api/users updated => /users updated",
        "/score::find => score-api/score::find",
        "/match::find => score-api/match::find"
      ]
