ADT: in NPW check for existing project name must be case-insensitive.

At least on Windows trying to create a project "Test1" when there's
an existing "test1" in the Eclipse workspace will fail to create the
project but currently goes undetected in the NPW.
This properly checks all projects names in a case-insensitive manner.

SDK Bug: b/8612400
