mtest: log test start in verbose mode
mtest: log test start in verbose mode

In non-parallel verbose mode the output of the test/benchmark
is not buffered, therefore the command line is only printed by
ConsoleLogger for failing tests and only after the test has run.

Verbose mode is designed mostly for CI systems, where output must
be human readable but is generally consumed from a browser with "Find"
commands rather than from a terminal.  With this usecase in mind, it
is better to provide as much detail as possible, so add more output
and just tell the user which tests have started.  Do so, using the
recently introduced TestResult.RUNNING state.
