 Improve 'alias_of' handling in wp_insert_term() and wp_update_term().

 Using get_term_by() rather than direct SQL queries to fetch the alias term
 fixes a number of issues:

 * Object cache for aliased term is properly cleared after update.
 * If the aliased term is in the object cache, it's served from there,
 saving a database query.
 * Duplicate 'edit_terms' and 'edited_terms' hooks can be removed.
 * Fix a PHP notice when the 'alias_of' term is not found.
 * Prevent the incorrect creation of a new term group for the primary term
 when the 'alias_of' term is not found.

 Adds unit tests for 'alias_of' functionality in both functions.

 Fixes #29848.
