Invalid test after config added support for multilines

[berland]

As the config parser now supports statements over multiple lines through the backslash operator, the following code:

ert/tests/ert/unit_tests/test_enkf_runpath.py

Lines 42 to 47 in 855c517

	def test_without_gen_kw(prior_ensemble, run_args, run_paths):
	with fileinput.input("snake_oil.ert", inplace=True) as fin:
	for line in fin:
	if line.startswith("GEN_KW"):
	continue
	print(line, end="")

does not work as intended on the input file:

ert/test-data/ert/snake_oil/snake_oil.ert

Lines 33 to 38 in 855c517

	GEN_KW \
	SNAKE_OIL_PARAM \
	templates/snake_oil_template.txt \
	snake_oil_params.txt \
	parameters/snake_oil_parameters.txt
