Remove logging dots per test step in AjcTest.runTest

Remove logging dots per test step in AjcTest.runTest

Methods AjcTest.runTest was logging something like "TEST: ...."
(4 dots), i.e. one dot per performed test step. Not only did this not
add much value, but due to usage of PrintStream.print for line
continuation it also messed up test step logging by scattering seemingly
random dot characters across test step logs. This looked quite ugly, so
I simply removed it.
