When seeking while player is idle, ensure EPII's position is in sync with EPI.
As soon as the seek gets acknowledged by EPII, EPI returns the actual position from the playback info again which is set by EPII. Thus, EPII needs to update the position to reflect the changes expected by EPI. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=182515106
