Split test logs on CI breaks with some node addresses

[ulope]

Problem Definition

It seems the tools/debugging/split_debug_logs.sh utility used in CI can't deal with some node addresses when they contain backslashes:

Processing logs without a node address
+ for test_directory in "${RAIDEN_TESTS_LOGSDIR}"/*
+ for log_file in "${test_directory}"/raiden-debug*.log
