If we try to parse a buildstats directory which was either aborted or
is still being built then the top-level build_stats file doesn't
contain an elapsed value which causes an exception:

UnboundLocalError: local variable 'elapsed' referenced before assignment

Default both start and elapsed to 0 so that the parse succeeds.
