There was an inconsistent behavior between saving a project file to disk (where the printer short name was readded after saving) and saving to the DigitalLibrary (where the printer short was NOT added again).
This commit fixes that by making sure that whatever the user put as the name of the file, will be the name of the project within Cura.

Instead of relying on the filename emitted when the workspace is changed. This is done so the user can also change the project name when saving to an output device, such as a local file, or the digital library, that supports changeing the (file)name.

No idea why this was there in the first place. Our archeology attempts couldn't
find out as to why it was introduced. We suspect an issue with other Qt versions.
At least now ロボット.stl will not be mangled into ロホット.gcode upon saving (and
german bears into bars)
This time we don't need to catch permission errors and such since we're reading it from a string that was stored in memory (read when the preferences file was read). However we do need to catch JSON Decoding Errors since the JSON syntax might be broken by the user modifying these files or because the file wasn't saved properly before.
Fixes Sentry issue CURA-112.
It was decided that functionality present in existing plugins is
sufficient. No need to replicate it in our own codebase and
take on the burden of maintenance
