NodeApp.make_empty fails when base_dir is None.

Exception has occurred: TypeError
join() argument must be str, bytes, or os.PathLike object, not 'NoneType'

During handling of the above exception, another exception occurred:

Attention

By default NodeApp uses CWD as (root) test path:

testgres/testgres/node.py

Line 2373 in 69f8d49

self.test_path = os_ops.cwd()

If you call NodeApp.make_empty (or NodeApp.male_simple) with empty base_dir (""), testgres will delete your current directory:

testgres/testgres/node.py

Lines 2382 to 2383 in 69f8d49

	real_base_dir = self.os_ops.build_path(self.test_path, base_dir)
	self.os_ops.rmdirs(real_base_dir, ignore_errors=True)

CWD may be a path to your a copy of testgres project or your application.
