Subject: [PATCH 1/2] Consider symlink when saving localconfig.php (see #2209)

Description
-----------

We are using [Deployer](https://deployer.org/) to deploy our Contao 4 instances. In the config, we have added

```
system/config/localconfig.php
```

to the `shared_files` so that any changes to the system config in the back end do not get lost after the next deployment. However, this does not actually work as Contao simply overwrites the symlink with a regular `localconfig.php` file when saving.

This PR changes that: it evaluates the `realpath` of an existing `localconfig.php` and uses that path as the new destination.

3d6582b6 Merge branch '4.4' into consider-symlinks-for-localconfig
5a895ca5 remove unnecessary file_exists call

`realpath` already checks for the existence of the file and returns `FALSE` in that case.

Subject: [PATCH 2/2] Fix picker deselecting filtered elements (see #2296)

Description

| Q                | A
| -----------------| ---
| Fixed issues     | Fixes #1816
| Docs PR or issue | -

This PR fixes the picker deselecting elements that are not visible any more due to filtering. It injects the previously selected elements for the `Backend.openModalSelector` JavaScript, which can then add or remove elements.
