Fix a TypeError on OC\Files\Cache\QuerySearchHelper::getCachesAndMoun…

[ajabep]

• Resolves: a bug that comes SOOOOOOO many times on my server.

Summary

Just an error by using LazyRootFolder :)

I added to OCP\Files\IRootFolder the signature of *mount and getMount* method and make OC\Files\Cache\QuerySearchHelper::getCachesAndMountPointsForSearch() requiering an OCP\Files\IRootFolder instead of a OC\Files\Node\Root.

Formated log of the error which occurs SOOOOOOOOO many times (deployed via NextCloud-AIO):

Checklist

• Code should be properly formatted (linted using php -l and tested in prod on my server)
• Sign-off message is added to all commits
• Tests (unit, integration, api and/or acceptance) are not included. I am currently testing it on my server, and it seems that does not break. I also have doubt about the presence of unit testing on this topic, else, the TypeError should never become in prod.
• No screenshots before/after for front-end changes: not a UI change.
• No Documentation (manuals or wiki) is required: not a new feature.
• No Backports requested, but feel free to request it.
