Editing or deleting the expiration date of group shares is not possible

[ScharfViktor]

steps:

• create space
• share space to group "philosophy haters" with expiration date
• try to edit or delete "expiration date"

Actual: no buttons Edit expiration date and remove expiration date for group sharing

Expected: same as sharing with user

This seems to affect regular resources as well, not only spaces.

here is backend issue. I re-opened #owncloud/ocis#5442
Perhaps the web doesn't see the button because response doesn't contain expire date
