Fix regression introduce in fix for bug #67118

The fix was correct but break some code (at least in Horde)
This is a temporary workaround to fix regressioni in 5.4, 5.5 and 5.6

This make php_date_initialize more consistent
- on success return 1 + time initiliazed
- on failure return 0 + time = zero
  which is check by DATE_CHECK_INITIALIZED by later method call

Will restore consistency with other date classes in master.
