cubicweb #4306081 [wsgi] POST only the last value of multiple variables is read [validation pending]

When posting an ajax call for example, a variable 'arg' is sent for each argument:

fname=complete_list&pageid=xxx&arg=9&arg=12&arg=xxx

The wsgi adapter will 'see' only the last arg value instead of an array.
