Steps to reproduce the issue:

  - Create files `a` `b` `c` with the following content:

    $ head a b c
    ==> a <==
    b

    I'm A
    ==> b <==
    c

    I'm B
    ==> c <==
    I'm C

  - Run `emancs a` to open bufer `a`
  - Press `gf` to jump to bufer `b`
  - Press `gf` to jump to bufer `c`
  - Press `C-o` to jump back to bufer `b`
  - Press `C-o` to jump back to bufer `a`
  - Press `C-i` to jump foward to bufer `b`
  - Press `C-i` to jump foward to bufer `c`, but the window stays with
    buffer unexpectedly.

In the absence of `:group`, `defcustom` and `defface` default to
the group that was last defined in the same file.

* evil-jumps.el: Remove redundant `:group` args.

* evil-jumps.el: Remove redundant `:group` args.

Add `evil--jumps-current-file-name` that returns `default-directory`
in `evil--jumps-push` when dired-mode is active.  The
`dired-directory` can be properly re-opened by `find-file` called by
future evil-jump-backward or evil-jump-forward.

This commit fixes some issues surrounding the initialization of Evil.

First of all, since GNU Emacs 26.1 major mode hooks actually do run in
Fundamental mode buffers. In any case, manually enabling
fundamental-mode correctly instead of turn-on-evil-mode (by setting
major-mode default) successfully enables evil-local-mode, as major mode
hooks then run. The major-mode variable also never needed to be reset;
it is the job of the major mode to set it, as it starts off as
fundamental-mode regardless of its default value.

Secondly, while some hooks and variables set up by evil-local-mode were
marked as permanent, this did not matter as evil-initialize
unconditionally reinitialized evil-local-mode whenever the major mode
changed. Fixed by marking them all as permanent and not executing
evil-local-mode if it is already enabled.
