If the "h" extension fails, give it another chance in main/pbx.c.

If the "h" extension fails, give it another chance in main/pbx.c, when it
returns from the bridge code.  Fixes an issue where the "h" extension may
occasionally not fire, when a Dial is executed from a Macro.
Debugged in #asterisk with user tompaw.
