User able to access incorrect urls/folders

[andavies]

eg. http://localhost:4000/projects/kjhkjhkj takes us to a broken project page

Seems to have resolved itself when local jekyll server restarted.

Leaving this issue open as a reminder when testing.

Occurs when collections output not set to true in _config.yml:

collections:
    projects:
        output: false

or

collections:
    projects:

We don't want user to be able to do this. We may wish to have collections that are not rendered.

The _config.yml master configuration file contains global configurations and variable definitions that are read once at execution time. Changes made to _config.yml during automatic regeneration are not loaded until the next execution.
