Subject: [PATCH] MDL-82214 admin: Settings should not change when in read only
 mode

Before this change if some settings were:

* read only
* visible on a settings page
* are set or have values selected

when the settings page was saved the setting would be set tobe empty,
because the hidden input remained on the page, while the other inputs
where not posted to Moodle.
