It is not obvious that timer handles are cleaned up properly when the current `Environment` exits, nor that the `Environment` knows to keep track of the closing handles. This change may not be necessary, because timer handles close without non-trivial delay (i.e. at the end of the current event loop term), and JS-based inspector sessions (which are the only ones we can easily test) are destroyed when cleaning up, closing the timers as a result. I don’t know what happens for other kinds of inspector sessions, though.
