terminalreporter prepends a newline on first write if tests are collected

Reproduce the behavior using the provided conftest.py and terminalreporter.section/write_line calls, once with no tests and once with a collected test. Trace the terminal reporter's first write and compare the output around the section header; done means the extra leading newline is absent while the reported sections and lines remain correctly formatted.
