Update keychains of ParseUser and ParseInstallation

[cbaker6]

In order to get this, User and Installation protocols have to implement it's own versions of some of the ParseObject methods. Not necessarily a problem, but adds more code to the ParseUser and ParseInstallation protocols. Also requires some additional testing outside of the ParseObject tests of these methods.

• updates keychain during fetch (Close User.current not returning all variables #37), fetchAll, delete, deleteAll
• add default callbackQueues to async Queries so user doesn't need to specify them
• Bug fix: during a synchronous save of a ParseObject if the parse-server returned a ParseError, the framework wouldn't complete on the current thread properly.
