Appbase passed to dnx cannot have trailing slash if there is no global.json

Repro steps:
(1) git clone Home repo
(2) cd Home/samples/ConsoleApp
(3) dnu restore
(4) dnx . run, works well
(5) dnx ./ run, fails with the following exception:

System.InvalidOperationException: Unable to resolve project 'ConsoleApp' from C:\AspNet\Home\samples\ConsoleApp\
   at Microsoft.Framework.Runtime.ApplicationHostContext..ctor(IServiceProvider serviceProvider, String projectDirectory
, String packagesDirectory, String configuration, FrameworkName targetFramework, ICache cache, ICacheContextAccessor cac

(6) Add a global.json to root of Home repo with the following contents:

{
  "projects": ["samples"]
}

Then dnx ./ run works.

@davidfowl , looks like a project dependency resolver bug? Need to investigate why there is difference between using . and ./ as appbase.

Is this a regression?

[ChengTian]

Yes, I remember I was able to run klr ./ run in KRE/samples/HelloWorld
