[file-search] The file search looks different on Windows and OS X

[kittaakos]

Depends on #1584.

Once the file search works on Windows and OS X, one has to check why the UI looks different on Windows than OS X. Originally from here

AC:

• The quick file search should look the same on all platforms.
• It should not show encoded URI segments: %40phosphor instead of @phosphor.

Hint: one has to check whether we send URIs (as strings) back and forth between the frontend and the backend instead of FS paths.

OS X:

Windows:

[akosyakov]

Looks like results returned by the search are normalized via URI.

[kittaakos]

No, the picture is out-dated, the URI normalization is already fixed. The catch is; on Windows, it is a path, on OS X it is the file name and the relative path as a description.

could we close this one as #3749 was merged ?
