catapult: fix broken run-tests catapult tracing Commit 97f52862b1bd thought this block was misindented, but it was not; the indentation after that commit means we never log a catapult trace for individual commands. Also, we've never emitted the "end" trace line when the test was finished, so the trace viewer claims that these "did not finish", fixing that as well.

test: fix self._testdir to use the right mercurial library during testing Currently if you run tests from some other directory other than the `../tests/`, you will get a warning stating ``` warning: Testing with unexpected mercurial lib: mercurial (expected /tmp/hgtests.xxxxxx/install/lib/python/mercurial) ``` This is because the current directory being added to the 'PATH', if the `self._testdir != runtestdir`, owing to this line ``` if self._testdir != runtestdir: path = [self._testdir] + path ``` Also say you ran the tests from the hg base directory, because directory is being added in the PATH (see the above snippet, at that stage the `self._testdir` has the value as `cwd`, owing to a faulty initialization). And since the current directory already has the 'hg', that is used in place of the hg that is installed for the testing purposes in `/tmp/hgtests.xxxxxx/...`.
