add-function potential bug

[star12thstar]

when I used add function, wanted to add a new phrase into chewing-editor, e.g. 多少錢, but I decided to cancel this action after typing 多少錢 in the blank of 詞彙, so I click cancel button. But when I re-opened the chewing-editor, 多少錢 is there! (I didn't find any reported issue related to the one i found, if it has been reported, please let me know, thx)

@Chocobo1 maybe we can also do this with https://github.com/chewing/chewing-editor/issues/83 ?

Auto clean the fields when adding Or auto fill the phrse from searchbox (for quick add non-exist phrase)
