bug#41285: 28.0.50; bibtex-Book not defined

[Shuguang Sun]

Dear,

When I run bibtex-Book (C-c C-e b) in bibtex-mode buffer, it is said
"command-execute: Wrong type argument: commandp, bibtex-Book".
I think it happened after       6bcf7912aad6312d4bd521a3b8b5d9638d83dfa1 
(patch), where it uses defalias to replace defun.
