* Fixed form mapper error where File objects were not being mapped correctly

Will now rely on `FormData` methods for catching erroneous objects being passed in - it may be worth working towards a more robust mapper for future use, but for now, it is felt that this version is more than suitable for our needs.

* Removed log statement

Missed a log statement that is no longer required - this has been removed
