bug#50245: 28.0.50; Instrumenting a function does not show "Edebug:" in the echo area

[Daniel Martín]

This is a regression from Emacs 27.2.

Steps to reproduce the problem:

1. emacs -Q
2. Place the point inside any Elisp function.
3. C-u C-M-x

Expected result:

"Edebug: <name of the function>" shows up in the echo area.

Actual result:

"<name of the function>" shows up in the echo area.  That makes it
difficult to know if the user evaluated or instrumented the function.

If you open the *Messages* buffer, the reason why we don't see it in the
echo area is because the "Edebug:" message is ovewritten by a subsequent
message that prints the name of the defun.
