Comment:

 In [changeset:"50692" 50692]:
 {{{
 #!CommitTicketReference repository="" revision="50692"
 Coding Standards: Remove unnecessary `unset()` calls in `WP_Importer`
 methods.

 Variables created within the scope of a function are discarded
 automatically when PHP leaves the scope of the function, i.e. on `return`,
 so doing a call to `unset()` straight before a `return` statement is
 redundant.

 Props jrf, ravipatel, rachelbaker, mukesh27.
 Fixes #52996.
