Incorrect merging of entries for German entries

[35122]

Currently glossaries for different readings of the same Kanji get merged together, for example 言質:

げんち's and げんしつ's glossary are merged, resulting in double the words and an annotation which tells one that the right reading is wrong. However this is not the case for all words, for example 人 works just fine

(this was made in assumption that the automatically generated dictionaries at https://foosoft.net/projects/yomichan/ also use yomichan-import)
