Do not pass '.' along as path

[rullzer]

Fixes #11637

When writing a file to the root of a shared storage we have to obtain
creatable information on the root of the share. However getting the
dirname of the path then results in .. Passing this along potentially
breaks.

For example objectstores do not have the same hierachy as a normal fs.
So the file . doesn't mean anything in that context.

i changed the jail.php like this:

	public function getUnjailedPath($path) {
		if ($path === '') {
			return $this->rootPath;
		} else {
			return $this->rootPath . '/' . $path;
			return Filesystem::normalizePath($this->rootPath . '/' . $path);
		}
	}

but after reloading my Nextcloud-Page, the erros still occures.

Replace it with

	public function getUnjailedPath($path) {
		if ($path === '') {
			return $this->rootPath;
		} else {
			return Filesystem::normalizePath($this->rootPath . '/' . $path);
		}
	}

i changed the jail.php like this:

Red lines in the git diff means "removed line" and green "added line".

ok, changed the code.

Now, when uploading or creating a file, there is no more error message, but the file does not appear and the "upload-bar" stays saying "a few seconds".

Stop, made a mistake: forgot to add use OC\Files\Filesystem;. After adding this line, it works!

You are great - thank you!

Have made this fix in a second instance and it works likewise.

Perfect!
