datetime: Enhance launching time of test_datetime by avoiding _reload_format() in...

visible_set() only changes the visibility of one field while _reload_format()
changes everything.

This patch makes visible_set() just change only related field when only it's state
is really changd(enabled <-> disabled) instead of calling _reload_format().
