Invalid cache before listing drive when collecting component names

[ethanwharris]

What does this PR do?

Can encounter a bug in the following setting (work a, work b, and a file server):

• work a - puts a file (creating a dir. under that works path)
• file server - gets the file (lists dirs and checks if any has the file, causing s3fs to cache the list of dirs, see: Add refresh to exists fsspec/s3fs#181 (comment))
• work b - puts a file
• file server - tries to get the file but can't see it because of outdated cache
