Fix selector path matching (#979)
## Description

Fixes an issue with the path matching logic in selectors where if the path was a substring of what was
specified as the scope in the filter, the item would still be matched.

e.g. 
Given 2 items - `/fold/contact1` and `/folderA/folderB/contact2` and a 
selector `er.Include(er.ContactFolders("AnyUser", []string{"folderA/folderB"}))`, 
the selector would match both items because `fold` is contained in the selector scope `folderA/folderB`

The fix is to invert the comparison - we check if the selector scope is contained in the item path instead.
In the example above, the selector string `folderA/folderB` will then only match the second items path.
