2026  * In the case of an actual copy/move (i.e. move/copy a folder between
2027  * accounts) tinymail uses the tny_folder_store_create_account which
2028  * is reimplemented by our ModestTnyLocalFoldersAccount that indeed
2029  * checks the new name of the folder, so this call in that case

2031  * implementation (if folder transfers within the same account is no
2032  * longer implemented as a rename) this call will allow Modest to work
