Prefer the prezto module format

to avoid conflicts when we have Zim modules made to also be compatible
with ohmyzsh, like https://github.com/zimfw/pvenv
We don't want to be affected by the noise a `${module_name}.plugin.zsh`
file creates, as we always want to source `init.zsh` when a module also
has a `functions` subdir. Hope this better protects us from the "wild
west out there".

+### Fixed
+- Prefer the prezto module format when using defaults to initialize a module.
+  This is the format we use in our Zim framework modules. It's is not well
+  documented anywhere officially, but in short words a prezto module has:
+  * a `functions` subdirectory that is added to the fpath by the framework,
+  * files inside the `functions` subdirectory that are autoloaded by the
+    framework (except for file names that match `_*` or `prompt_*_setup`),
+  * an `init.zsh` file that is sourced by the framework.
