bug#43260: 28.0.50; package-installed-p returns nil for tablegen-mode (not published in melpa) which is installed via quelpa

[Zhiwei Chen]

To reproduce:

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))
(eval-and-compile
  (setq use-package-always-ensure nil)
  (setq use-package-always-defer nil)
  (setq use-package-always-demand nil)
  (setq use-package-expand-minimally nil)
  (setq use-package-enable-imenu-support t))
(eval-when-compile
  (require 'use-package))

;; Bootstrap `quelpa'.
(use-package quelpa
  :ensure t
  :custom
  (quelpa-update-melpa-p nil)
  (quelpa-self-upgrade-p nil)
  (quelpa-checkout-melpa-p nil))

(use-package quelpa-use-package
  :ensure t
  :config
  (quelpa-use-package-activate-advice)
  :custom
  (quelpa-use-package-inhibit-loading-quelpa t))
  
;; LLVM IR
(use-package llvm-mode
  :ensure t
  :quelpa (llvm-mode :fetcher url
                     :url 
"https://raw.githubusercontent.com/llvm/llvm-project/master/llvm/utils/emacs/llvm-mode.el";)
  :mode ("\\.ll\\'" . llvm-mode))

;; TableGen description
(use-package tablegen-mode
  :ensure t
  :quelpa (tablegen-mode :fetcher url
                         :url 
"https://raw.githubusercontent.com/llvm/llvm-project/master/llvm/utils/emacs/tablegen-mode.el";)
  :mode ("\\.td\\'" . tablegen-mode))

Run:
  
M-: (package-installed-p 'tablegen-mode) RET

It returns nil for tablegen-mode while t for llvm-mode.
