Can't filter for all users of a site by access Write. All users are displayed even if Write is selected in the "Filter by access" field.

Steps to reproduce:

• matomo version 3.6.0
• php version 7.0.7
• open "Manage Users"
• select Write in the Filter by access field

Expected:

• only users with the role Write are displayed

Actual:

• all users are displayed
