Tags are not displayed on shared resources

[ScharfViktor]

after debugging tag.feature:178 in owncloud/ocis#10172 I found bug

use https://ocis.ocis-web.master.owncloud.works/

ocis | 6.4.0
web 10.3.0

Steps:

• admin creates space s1 and folder f1 inside the space
• admin adds tag1 and tag2 to folder f1
• admin shares folder f1 to einstein with edit permission
• einstein opens f1

Expected: einstein sees tags tag1 and tag2 to folder f1
Actual: no tags
