[EGD-5908] Fix bug in Logger + add log unit test

Because `vsnprintf` return value means:
"
The number of characters that would have been
written if n had been sufficiently large,
not counting the terminating null character.
If an encoding error occurs, a negative number is returned.
"

`Logger` crashed when log msg was longer than LOGGER_BUFFER_SIZE.
Checking `vsnprintf` return value solves this issue.
