Annoying bug in 2.6x Save project

[eldrick 65]

On my Mac w/ Sierra, attempts to Save Project more than once result in a very annoying and uninformative dialog box about having to save the project with the suffix "curaproject.3mf", and which results in misnamed filenames like mything.curaproject.3mf.curaproject.3mf or mything.curaproject.3mf.curaproject.3mf.curaproject.3mf no matter what button you choose in the dialog.

I also noticed this in 2.4 and the 2.6 beta. I've gotten into the habit of deleteng the ".curaprofile.3mf" out of the filename every time I save a project to prevent the repeating extensions. It looks like somebody else saw it in 2.4, too. It's in the GitHub issues Cura 2.4: Project's file extension #1485 https://github.com/Ultimaker/Cura/issues/1485
