operation-options: Set max to default_max if inferior to min
This MR is related to grilo-plugins!132 (merged) where the search doesn't work.
One of the reason is totem!340 (closed).
But the other reason, is that grilo doesn't handle the max value being inferior to the min in grl_operation_options_set_key_range_filter_value.
Not sure if this MR is the best way to fix it.
Please let me know if you want me to change it.
Thanks
