Error on startup: 'overlaps the location of another project'...

0.8.0, Linux 14.04

• Opening up VSCode on a folder containing the devoxx sample (https://github.com/fbricon/devoxx.git) gives me the following error:

Contains: /home/aeschli/workspaces/samples/devoxx overlaps the location of another project: 'devoxx'

• the underlying problem is that the hidden Eclipe workspace can only have a single project of a given name
• looks like I already opened some other project called 'devoxx' some time (that's possible)
• it would be good if the other location would be printed so we can find out if it's a valid conflict
• conflicts like that should not be the users concern:
  • a solution would be to always qualify all project names so they are unique
  • an other solution would be to always delete such duplicated projects (and rebuild them if they are used again later)

Rastreie o caminho de inicialização por InitHandler, ProjectsManager e MavenProjectImporter, usando a falha relatada de Project.checkDescription como ponto de partida. Determine como nomes de projetos duplicados são tratados e verifique se a inicialização não deixa mais o conflito sem explicação nem falha sem identificar o outro local.
