Subject: [PATCH 1/2] Remove unreqired backtick removal

Without this files with a ` (backtick) in the beginning of the filenames where simply not correctly referenced as the ` got removed. This can lead to all possible havoc situations.

Should get backported to stable8 and in future we might consider if it is really worth to backport such changes when it is just for SQLite :see_no_evil:
