* Hotfix for overwrite issue in 2.8.0  (#1838)

* This solution is an hotfix for overrite issue came back on 2.8.0 version. What I did is checking the extension, and if it is null, adding .jpg suffix. Because commons files always have suffixes, and we should compare file names after adding suffixes. Othervise overrides are possible.

* Check if file title includes an extension already, by checking if is there any dot in it.

* Fix logic error

* Add uncovered tests

* Remove unecessary line breaks

* Make Javadocs more explicit
