Node API: search operations don't work on the top folder of external shares

[oparoz]

Steps to reproduce

$folder = $this->rootFolder->get('/admin/files/mounted_external_owncloud')
$result = $folder->searchByMime('image')
var_dump($result);

Expected result

An array full of Files

Actual result

An empty result

Notes

Querying a sub-folder works...

$folder = $this->rootFolder->get('/admin/files/mounted_external_owncloud/subfolder')
$result = $folder->searchByMime('image')
var_dump($result);

This doesn't work:

core/lib/private/files/node/folder.php

Line 225 in 9883d5b

if ($internalRootLength === 0 or substr($result['path'], 0, $internalRootLength) === $internalPath) {

if ($internalRootLength === 0 or substr($result['path'], 0, $internalRootLength) === $internalPath) {

with

$internalPath = rtrim($internalPath, '/') . '/'; <------- Minimum size is 1
$internalRootLength = strlen($internalPath) = 1

which can never match 0
