Modifying a task's project name to a string starting with "project" does not work

Before anything else: Thank you for this amazing task manager. I've been using it quite a while now and I love it!

* What command(s) did you run?
* `task add pro:foo bar task` -> generates task 1
* `task 1 modify project:"project-new"`
* What did you expect to happen?
I would expect that the task's project changes to "project-new"
* What actually happened?
The task's project changed to "foo-new"
* Paste the output of the ```task diag``` command.

Is this desired behavior? I mean, it sounds reasonable that you can reference the task's project name, but simply replacing the word "project" with the project name seems a bit much for me.
