clan_cli flake: remove apply from select, as it will break stuff in horrible ways

Since apply changes the structure of the retuned value, the cache will
be confused about the structure and in subsequent request will use this
wrong structure.

For example: we would use builtins.attrNames on inputs, the flake will
forever think that inputs is a list of strings and will report errors
whenever we try to fetch subkeys from it
