* issue 458.2.1: ensure LogicalCollection presence is checked before granting/revoking permissions
* try to address test failures
* backport: support wildcard for database too
* create collection before granting
* adjust ruby tests to expect behaviour as defined by issue #458
* adjust expected Ruby test result
* create required collection in Ruby test
* revert back to previous test code since Ruby refuses to create required collection
* missed revert
