Remove allowed argument check

the check results in an 'OaiException' with message 'Bad argument: start: 0'
for paging the 'start' filed is part of the '' but this is not part of the allowed arguments 'from,until,metadataPrefix,set,resumptionToken'

the implementation is otherwise ok, only the check does not fit
