Automated rollback of changelist 166843123.

*** Reason for rollback ***

Doesn't work because trackOutputProvider can be null when extracting init data.

*** Original change description ***

Don't copy primary-track format to non-primary tracks

Copying non-primary-track formats to non-primary tracks
looks non-trivial (I tried; went down a dead-end), so
leaving that for now.
