Add taxonomy argument to get_terms_orderby filter

[johnbillion]

The get_terms_orderby filter in get_terms() doesn't get passed the taxonomies parameter.

If a plugin wants to use the taxonomies parameter when filtering the terms order, it must also filter get_terms_args and add the taxonomies argument to the $args array, so it can subsequently use it in the get_terms_orderby filter.

Patch

Easy fix, patch still applies

Patch works for me too.

18754.diff​ is a refresh, plus it passes $taxonomies to the other filters used in get_terms() (props nacin for pointing those out).

Not going to use the latter patch that passes $taxonomies to the other filters too?

[nacin]

Ah, didn't see it.

list_terms_exclusions is a weird filter. Does this affect any of the issues covered in #21267? Don't think so, but want to check.

Pass $taxonomies to two more filters in get_terms().
