LDAP User A shares with LDAP User B. LDAP Server for user B leaves to be available. The permissions of the checkboxes should be disabled

Steps to reproduce

1. As admin enable LDAP app
2. In LDAP section enable two LDAP configurations
3. Share a file from a user of LDAP A to a user of LDAP B
4. Make LDAP B server backend not accesible changing the data written in the LDAP wizard with a wrong one

Expected behaviour

The checkboxers of the share permissions are disabled.

Actual behaviour

The checkboxers of the share permissions are enabled. Clicking on them an error is thrown

Reproduce the two LDAP-configuration scenario, make LDAP B unavailable, and inspect the share-permission update through the mentioned OCS shares API endpoint. Confirm that the permission checkboxes are disabled when the recipient backend cannot be reached and that clicking them no longer produces an error.
