Freezes emacs in daemon mode

[bjornbm]

From https://github.com/syl20bnr/spacemacs/tree/master/layers/%2Bcheckers/spell-checking#enabling-auto-dictionary-mode:

Some people encountered bugs with auto-dictionary-mode, especially in daemon mode where new emacsclient open directly freezed. If so, no other workaround have been found yet than disabling auto-dictionary-mode completely.

Happens for me too. See also syl20bnr/spacemacs#11502.
