options.process is undefined, even though it's defined.

I'm migrating from the grunt-typescript plugin to grunt-ts right now. I've run into this issue with grunt-contrib-concat, which had now problem until I switched to grunt-ts.

I've opened the issue there, but I'm not familiar enough with grunt nor grunt-ts to know whether it should've been opened here or there. So I'm opening it here as well. Please close if it doesn't belong here.

I have all the other tasks working as expected right now, but when trying to use a process function in the concat task, it's undefined and fails. When I comment out the options block, it executes successfully.

What's wrong here?

grunt-ts version: `5.5.1`

grunt-contrib-concat version: `0.4.0`
