Add EOL after test message

[skocjan]

If TEST_ASSERT_*_MESSAGE() is used and fails, next message is printed on the same line without EOL. This change should improve the readability of output.

Hi @skocjan -- what is the situation you're running into where this line ending was necessary? Normally, a line ending is automatically added in UnityConcludeTest after each test, so that the individual functions and macros don't have to add it themselves. This will be true no matter if a custom message has been added or not. I'm assuming, though, since you've attempted to fix something, that you've seen a problem in some configuration. Can you tell me more about what you're seeing and what your configuration is?

Hi @mvandervoord , thanks for explaination. My configuration is a cross compilation to TI ARM platform and to be honest, it must've been some misinterpretation from my side, because now, when I have it properly integrated, I cannot see the issue anymore. Sorry for the noise and PR can be closed
