Fix the way `detect_common_display_methods` finds label & value methods

It was previously looking at an instance of the `collection` instead of the
`collection_classes`. Since the grouped collection input supplies a list
of collection classes that differ from the regular collection, it was
incorrectly looking for labelling and value methods on the option
instances, rather than the optgroup instances.
Added the ability consider whether the the user exlicitly specified the label or the framework generated it when applying global custom formatting.
Cache the test for parameters size of label_text for better performance.
Changed call to label_text to always pass the new thrid parameter, and made the default a proc that ignores it. This is a breaking change.
