fix initwrite behaviour

with handlers, a parameter from the cfg file which is not the
first of parameters with the same handler were not written.
fix: write_<param> method is called for all parameters in
<module>.writeDict even if there is no poll entry.

with this fix, when a parameter has the property initwrite=True,
the write_<param> method is called even when <param>
is not polled and even when <module>.pollerClass is None
