Docz: [TypeScript] Props cache is cleaned on each start

[Kerumen]

Bug Report

Docz populates a .docz/.cache/propsParser.json at the first run. It avoids unnecessary props parsing for future launches. It's done on that file: https://github.com/doczjs/docz/blob/master/core/docz-core/src/utils/docgen/typescript.ts
However, (since Gatsby ?), each docz files are "called" 2 times. First, from the project folder, and then, from the .docz folder.

On first run, nothing is called but the getInitialFilesMap() function because it's declared at the root of the file. It reads the cache and removes every files that is invalid. As the cache is populated "from" the .docz folder, paths are invalids and everything get removed.
Then, from Docz, the file is inited again (getInitialFilesMap() too but there is nothing in the cache to remove) and the props are populated with relative path from the .docz folder because the function tsParser is called (it was not during the first run).

To sum up, we should not call getInitialFilesMap from the project folder but only from the docz folder, within the tsParser call. I tried to move it before the loadFiles call (L186) because it's the only function that needs the filesMap and it worked but I don't know the side-effects as my knowledge on this part of the code is limited :neutral_face:

@Kerumen is there any workaround to getting this to work? Every build takes a very long time right now :(
