[BUGFIX] Prevent duplicate '/' in filepath when uploading file

To prevent a duplicate '/' in a filepath the function
LocalDriver::getAbsolutePath should be used instead of
concatenating strings by hand.
This fixes also an issue that file uploads are not
possible on windows machines due to a incorrect filepath.

Resolves: #65230
Releases: master, 6.2
