Revert "Timer::Start must be called with SolarMutex locked"

This reverts commit 1c3e88a4ffd927d4dda8bb9e0d05cddc6cd685c0; the static
AutoRecovery instance is only destroyed during exit, but wants to use
SolarMutex; that causes crashes at least in CppunitTest_services.  Apparently
needs more thought.
