Early `textDocument/didOpen` misses parent module origin collection

[radeksimko]

In case where the user opens the editor with restored session, where files were previously opened, or simply opens a file early, before we manage to finish indexing the workspace via walker, we may end up without reference origins on the module block. Therefore Go-To-Definition doesn't work on first load and requires re-opening the file or typing something into it.

Collecting origins on module blocks requires the module itself being parsed & metadata decoded beforehand.

The theory is that the reference origin collection for the config with the module block runs earlier than expected, due to it being prioritised over the parsing and metadata decoding of the called module code itself.
