Fix NoReverseMatch when project_name is empty

[amustapha]

Description

Currently, when a project name is empty the reverse url method raises a NoReverseMatch error. This can prevent customers from temporarily being able to access the system. A quickfix could be to modify defaulting instances but a more longterm solution would be to allow null project_name. This is done by

1. Creating a new url path that doesn't accept project_name
2. Check if a project has a name, if it doesn't do not include empty string in the kwargs

Nice! Just one little typo, but looks great
