Commit 63205981 removed some events but left all other event IDs at their original values, which created "holes" at the events IDs array. The JS backend for mp.register_event maps a name to an ID by scanning all IDs and stopping when the name was found or a NULL name was returned. Lua does the same except that it doesn't stop on NULL name. Previously it was not possible to have a NULL name before the end of the array, but now it is possible due to the enumeration holes. Fix by skipping missing names, like lua does.
