Regression when renaming incoming shares

[juliusknorr]

There seems to be a regression from #36047 where renaming shares is not working properly anymore.

Steps to reproduce:

• Share a file from A to B
• Login as B
• Rename the file
• Reload the file list

Expected:

• The new name should be shown

Actual:

• The old name is still shown

I've switched memcache.local to redis to be able to inspect the key

from what I see the cached value still has the old path name

it seems we're missing some invalidation code, however I'm not sure how it could have worked before...

ok, so the reason it worked before was because the share target changed, so this made it use a different cache key
after each rename
