Installation of extensions fixes

Installation of extensions fixes
- Again some extensions has not been fully rewritten to newly introduced
  wrapper functions which caused them to not install
- An extra back-tick (`) was found in column name :(
- Added optional $forceFound variable which can be used to (if the table is
  missing) that the column/key is marked as "found"
- Expanded debug messages with column/key name and $forceFound variable
- TODOs.txt updated
