mgr/PyModule: do not lock in get_name()

The way get_name() used the lock is completely wrong: in the protected
code block, it do not access anything that needs to be protected.  All
it effectively does is return the `this` pointer with an offset to the
`module_name` field; but it does not actually access the field.  The
actual access is done by the caller, after the mutex has been unlocked
already.

But anyway, `module_name` does not need any protection.  It is `const`
and thus cannot be modified by other threads.  So instead of fixing
the return value (removing the `&`), let's just remove the lock.
