differentiate quicksetup based on project folder

[DropD]

Problem:

When using quicksetup with a custom location for the .aiida/ config folder, it might try to create and use an existing dbuser with a new password, causing naive use of quicksetup to fail.

Solution:

Add a uuid of the current AIIDA_PATH folder to the db user and db name during quicksetup.

I get that it makes sense to use a different DB for different config folders.
If the DB is already different, do we still need to append the hash to the username?

[DropD]

In fact the username is just as important: if it already exists (from another config.json), there is no way to know the password stored in the other config.json.

Ah right, I forgot that the user names are system-wide.
