Add unit tests uncovering improper UNC paths resolution

Browse source 
While resolved paths always contain the `\\?\` prefix, it's not always
correct to strip only those 4 chars. In case of UNC paths, the prefix
is actually a bit longer (`\\?\UNC\`) and needs to be replaced with `\\`
instead.

Failing to do so results in invalid paths, e.g. `\\Host\Share\File` becomes
`UNC\Host\Share\File` which totally wrong.
