Symfony version(s) affected: 4.3.2

Description
Profiler trace gives wrong url with Symfony hosted in a subdirectory.
Say Symfony is hosted in http://localhost/mysymfonyroot/.
Profiler trace will give links such as http://localhost/mysymfonyroot/mysymfonyroot/_profiler/open?file=public\index.php&line=25#line25, giving twice the subdirectory name.

How to reproduce
Install Symfony in a subdirectory.

Possible Solution
Remove $request->getBasePath() from getFileLinkFormat() method, as it's already generated by generateUrlFormat().
