commit 47a220d521b9fb916f0d51da2df229a9ff7870b7

    Support hash tables in ivy-read
    
    * ivy.el (ivy--reset-state): `all-completions' also works fine for hash
      tables, so start using it.
    
    Hash tables as collections are rare. One example is "C-c C-w"
    in *rcirc* (`rcirc-cmd-whois').
