Title: Update ProjectReactorValidator.java

I just turned off the auto-creation of projects, so entered this if statement and encountered the exception.
The project key is project:branch, not project alone ie my project key is mediagraft:master.

By re-enabling the automatic creation of projects, ie not entering this if statement, the project works again.
