[2.0.1] Paths resolving incorrectly when `baseUrl:''`

[TheLarkInn]

ATL Version: 2.0.1
Typescript Version: typescript@next

Expected Behavior: When you set baseUrl to an empty string (''), it should default to path.dirname(configFilePath).

Actual Behavior: Currently instead of being the path relative to the config file, it is resolving to the directory that the process was run in (process.cwd()).

Below is a small illustration showing the concern.

I will hopefully get a PR in once I've verified it fixes the problem.

PS. Paths should be ignored when the baseUrl property is NOT in the config, however should still work when baseUrl:''

@DanielRosenwasser sounds right?
