Added test for TeX includes with same name as subdirs.

This is the same problem as Issue 1953:
  error: DirNodeInfo instance has no attribute 'csig'
except in a less central location.  I recycled John Gozde's CPPPATH
test for the new problem.

+This is an obscure test case. When
+  1) a file without a suffix is included in a TeX build and
+  2) there is a directory with the same name as that file,
+verify that a TypeError is not thrown upon trying to recursively scan
+the contents of includes. The TypeError indicates that the directory
+with the same name was trying to be scanned as the include file, which
+it clearly is not.
