In 8f4e5c8194 the `DiagnosticReporter` was cached in
`DevCompilerTarget` which introduced a memory leak.
Unfortunately our weekly bot that looks for leaks has been out of
commission, but is now coming back online.
This CL fixes the leak by overwriting the field every time, meaing we
don't save a reference to the first one (which is a leak).
Maybe ideally we shouldn't save it as a field at all, but that's a
potential for another day.
