snapshot should wait for isReady

[ronag]

RecordHandler.prototype.snapshot = function( name, callback ) {
    if( this._records[ name ] && this._records[ name ].isReady ) {
       callback(null, this._records[ name ].get() );
    } else {
        this._snapshotRegistry.request( name, callback );
    }
};
