Scanning a directory that contains a .dll results in the directory and all files being deleted

When a directory is passed to the TemplateCache Scan method, and a subdirectory contains .dll files, then the directory and all files are deleted. When scanning a directory this should not happen since this may contain the original project and associated template files.

I created a simple console app that uses the IDE Bootstrapper to reproduce the problem:

https://github.com/mrward/TestDotNetTemplateInstaller

Building and running this console application results in the TestDotNetTemplateInstaller project directory being deleted. This was tested on the Mac with Mono 5.4.

Debugging the TemplateCache what happens is that when a .dll file is found then the directory is deleted in the ScanForComponents method.

The dotnet cli does not seem to have the same problem. Running dotnet new -i /path/to/template using a directory that has a template.json but also .dll files in a subdirectory works as expected and no project files are removed.
