MultilineCommentLocator returns invalid PhraseLocation when end delimiter precedes start

[polarian]

Description

MultilineCommentLocator.locate() returns PhraseLocation with start > end when end delimiter (*/) appears before start delimiter (/*).

Reproduction

val result = MultilineCommentLocator.locate("*/path/*")

Expected

Return empty set when no valid comment exists.

Actual

Returns PhraseLocation with reversed range (start > end).
