widget.py: Avoid extra empty lines when message-lines or error-lines is 0 - #2208

…is 0 With message-lines set to 0, the detail of a message is truncated away entirely, but LogLine still prints an empty line, a line with only the indentation and another empty line after the message. Likewise, a failure message in verbose mode with error-lines set to 0 skips the log tail, but is still followed by two empty lines instead of the usual one. Only print the message detail when some of it is left, and only add the newline that introduces the failure details when they are printed. Failure messages keep the single empty line that separates them from the next message, and from the next entry in the failure summary. Fixes apache#2145
Render messages with LogLine and check that no empty lines are left behind when message-lines is 0, that a truncated message still reports how many lines were left out, and that a failure message is followed by a single empty line when error-lines is 0. This is a part of apache#2145

With message-lines set to 0, the detail of a message is truncated to nothing, but LogLine still prints an empty line, a line holding only the indentation and another empty line after the message. A failure message in verbose mode with error-lines set to 0 is followed by two empty lines instead of one.
The detail is now only printed when some of it is left, and the newline before the failure details is only added when they are shown. Failure messages keep their single trailing empty line, so entries in the failure summary stay separated. Output is unchanged when both options are non-zero.
I added tests in tests/frontend/logging.py that render messages through LogLine, and ran tests/frontend, black, pylint and mypy locally.
Fixes #2145
