It does. In Matthias's example:

 (module imp test

a `#%module-begin' is wrapped around the `1', and the generated
`#%module-begin' form does get the property.

In your original test,

 (test-module-name)      ; => #f

there's no module wrapping the expression, and hence no
`#%module-begin'. Indeed, there is no enclosing module at all.

It's possible that either `syntax-identifier-binding' or
`syntax-source-module' will do what you want, but I'm not sure.
