Fixed races not loading when event type is not defined

Old code was:

Fixes #2745

@only-a-ptr Is this correct or we need to be specific? Like

if strncmp(ev_type, "",  0)

Let's leave it like it is, I think it's the best solution.

The old parser was somewhat messy here - If the filter-string was bogus but not empty, the filter would be set to value of previous event filter (or EVENT_ALL for the very first event line). But I think this is an old bug and it really should behave the way you made it just now.
