Improve error handling in `get_categories()`. 

When passed an invalid `'taxonomy'`, `get_terms()` will return a `WP_Error`
object. This object should not be blindly cast to an array. Instead, an empty
array should be returned, to indicate that no matching terms have been found.

Props virgodesign, sebastian.pisula.
